On the A64 the clock for the first USB controller is actually the parent
of the clock for the second controller, so turning them off in that order
makes the system hang.
Fix this by only turning off *both* clocks when the *last* OHCI controller
is brought down. This covers the case when only one controller is used.

Masking clock gate, reset register bits based on the
probed controller is proper only due to the assumption
that masking should start with 0 even thought the controller
has separate PHY or shared between OTG.
unfortunately these are fixed due to lack of separate
clock, reset drivers.
Say for example EHCI1 - EHCI3 in the datasheet (EHCI0 is for the OTG)
so we need to start reg_mask 0 - 2.
This patch calculated the mask, based on the register base
so that we can get the proper bits to set with respect to
probed controller.
We even do this masking by using PHY index specifier from dt,
but dev_read_addr_size is failing for 64-bit boards.

For ohci, the maximam supported endpoint number is 32(in and out), and
now we have used (usb_pipeendpoint(pipe) << 1) to index the specified
endpoint descritor, usb_pipeendpoint(pipe) can reach 0xf, so we need
change the NUM_EDs from 8 to 32.

This bug is the combination of dwc2 USB controller and lan78xx
USB ethernet controller, which is the combination in use on
the Raspberry Pi Model 3 B+.
When the host attempts to receive a packet, but a packet has not
arrived, the lan78xx controller responds by setting BIR
(Bulk-In Empty Response) to NAK. Unfortunately, this hangs
the USB controller and requires the USB controller to
be reset.
The fix proposed is to have the lan78xx controller respond
by setting BIR to ZLP.

If a full speed hub connects to a high speed hub which supports MTT,
the MTT field of its slot context will be set to 1 when xHCI driver
setups an xHCI virtual device in xhci_setup_addressable_virt_dev().
Once usb core fetch its hub descriptor, and need to update the xHC's
internal data structures for the device, the HUB field of its slot
context will be set to 1 too, meanwhile MTT is also set before, this
will cause configure endpoint command fail. In the case, we should
clear MTT to 0 for full speed hub according to section 6.2.2.

If a USB 3.0 hub is plugged into the root port of the xHC, the xHCI
driver will issue a 'Configure Endpoint' command to the xHC for it
to update its internal data structure for this hub device. The hub
attributes are in the slot context so we need tell xHC to update the
slot context by setting the add context flags of the input control
context to only cover the slot context.
At present the add context flags is or'ed with the slot context bit,
but it should really be accurately set to the slot context, as the
variable that holds the value of the add context flags comes from
whatever was set in the last command execution, which may contain
additional contexts that 'Configure Endpoint' command should not
touch. Some xHC implementations like x86 don't complain such, but
it was observed on Renesas RCar Gen3 platform that the RCar xHC
complains with a 'TRB error' completion codes as the response.
