In preparation to adding of_i2c_setup_smbus_alert() move
i2c_setup_smbus_alert() to core module. of_i2c_setup_smbus_alert()
will call i2c_setup_smbus_alert() and this avoid module dependecy issues.

Prior to this commit the smbalert_irq was handling in the hard irq
context. This change switch to using a thread irq which avoids the need
for the work thread. Using threaded irq also removes the need for the
edge_triggered flag as the enabling / disabling of the hard irq for level
triggered interrupts will be handled by the irq core.
Without this change have an irq connected to something like an i2c gpio
resulted in a null ptr deferences. Specifically handle_nested_irq calls
the threaded irq handler.
There are currently 3 in tree drivers affected by this change.
i2c-parport driver calls i2c_handle_smbus_alert in a hard irq context.
This driver use edge trigger interrupts which skip the enable / disable
calls. But it still need to handle the smbus transaction on a thread. So
the work thread is kept for this driver.
i2c-parport-light & i2c-thunderx-pcidrv provide the irq number in the
setup which will result in the thread irq being used.
i2c-parport-light is edge trigger so the enable / disable call was
skipped as well.
i2c-thunderx-pcidrv is getting the edge / level trigger setting from of
data and was setting the flag as required. However the irq core should
handle this automatically.

SMBUS_BLOCK_DATA transactions might fail due to a race condition with
the IMC (Integrated Micro Controller), even when the IMC semaphore
is used.
This bug has been reported and confirmed by AMD, who suggested as a
solution an IMC firmware upgrade (obtained via BIOS update) and
disabling the IMC during SMBUS_BLOCK_DATA transactions.
Even without the IMC upgrade, the SMBUS is much more stable with this
patch.

Commit b6c159a9cb ("i2c: ismt: Don't duplicate the receive length for
block reads") broke I2C block reads. It aimed to fix normal SMBus block
read, but changed the correct behavior of I2C block read in the process.
According to Documentation/i2c/smbus-protocol, one vital difference
between normal SMBus block read and I2C block read is that there is no
byte count prefixed in the data sent on the wire:
SMBus Block Read: i2c_smbus_read_block_data()
S Addr Wr [A] Comm [A]
S Addr Rd [A] [Count] A [Data] A [Data] A ... A [Data] NA P
I2C Block Read: i2c_smbus_read_i2c_block_data()
S Addr Wr [A] Comm [A]
S Addr Rd [A] [Data] A [Data] A ... A [Data] NA P
Therefore the two transaction types need to be processed differently in
the driver by copying of the dma_buffer as done previously for the
I2C_SMBUS_I2C_BLOCK_DATA case.

According to Table 15-14 of the C2000 EDS (Intel doc #510524) the
rx data pointed to by the descriptor dptr contains the byte count.
desc->rxbytes reports all bytes read on the wire, including the
"byte count" byte. So if a device sends 4 bytes in response to a
block read, on the wire and in the DMA buffer we see:
count data1 data2 data3 data4
0x04 0xde 0xad 0xbe 0xef
That's what we want to return in data->block to the next level.
Instead we were actually prefixing that with desc->rxbytes:
bad
count count data1 data2 data3 data4
0x05 0x04 0xde 0xad 0xbe 0xef

In addition to the base, low and high clock configuration, the AC timing
register #1 on the AST2400 houses fields controlling:
1. tBUF: Minimum delay between Stop and Start conditions
2. tHDSTA: Hold time for the Start condition
3. tACST: Setup time for Start and Stop conditions, and hold time for the
Repeated Start condition
These values are defined in hardware on the AST2500 and therefore don't
need to be set.
aspeed_i2c_init_clk() was performing a direct write of the generated
clock values rather than a read/mask/modify/update sequence to retain
tBUF, tHDSTA and tACST, and therefore cleared the tBUF, tHDSTA and tACST
fields on the AST2400. This resulted in a delay/setup/hold time of 1
base clock, which in some configurations is not enough for some devices
(e.g. the MAX31785 fan controller, with an APB of 48MHz and a desired
bus speed of 100kHz).

The Cherry Trail Whiskey Cove PMIC's IRQ line is attached to one of
the GPIOs of the Cherry Trail SoC. The CHT GPIO controller sometimes
fails to deliver IRQs (seen when there is an IRQ storm on another pin).
This commit works around this by reducing the long timeout which was
a poor attempt to workaround this from 3s to 30ms and after that
manually checking the status register for transfer completion by
calling the threaded IRQ handler directly.
This is safe todo as the entire threaded IRQ handler is protected
by a mutex.
Note 30ms should be more then long enough, at 100KHz any smbus single
byte transaction should be finished in 4ms.

I guess pm_runtime_put_noidle() call in i2c_dw_probe_slave() was copied
by accident from similar master mode adapter registration code. It is
unbalanced due missing pm_runtime_get_noresume() but harmless since it
doesn't decrease dev->power.usage_count below zero.
In theory we can hit similar needless runtime suspend/resume cycle
during slave mode adapter registration that was happening when
registering the master mode adapter. See commit cd998ded5c ("i2c:
designware: Prevent runtime suspend during adapter registration").
However, since we are slave, we can consider it as a wrong configuration
if we have other slaves attached under this adapter and can omit the
pm_runtime_get_noresume()/pm_runtime_put_noidle() calls for simplicity.
