If we don't assign Moorestown specific wallclock init and ops function
the rtc/persisent clock code will use cmos rtc for access, this will
crash Moorestown in that the ioports are not present.
Also in vrtc driver, should avoid using cmos access to check UIP status.

There are 3 places defining similar functions of saving IRQ vector
info into mp_irqs[] array: mmparse/acpi/mrst.
Replace the redundant code by a common function in io_apic.c as it's
only called when CONFIG_X86_IO_APIC=y

When setting up the mpc_intsrc structure for vRTC's IRQ,
we need to set its irqflag to level trigger, otherwise
it will be taken as edge triggered and the vRTC IRQ will
fire only once, as there is never a EOI issued from the
IA core for it.
The original code worked in previous kernel. This is because it
was configured to level trigger type by luck. It fell
into the default PCI trigger category which is level triggered.

This patch adds the sound card bindings for Moorestown (pmic_audio) and
the Medfield platform (msic_audio) as IPC devices. This ensures they will be

Moorestown platform doesn't have a m146818 RTC device like traditional
x86 PC, but a firmware emulated virtual RTC device(vrtc), which provides
some basic RTC functions like get/set time. vrtc serves as the only
wall clock device on Moorestown platform.

Penwell has APB timer based watchdog timers, it requires platform code to parse
SFI MTMR tables in order to claim its timer.
This patch will always parse SFI MTMR regardless of system timer configuration
choices. Otherwise, SFI MTMR table may not get parsed if running on Medfield
with always-on local APIC timers and constant TSC. Watchdog timer driver will
then not get a timer to use.

SFI provides a series of tables. These describe the platform devices present
including SPI and I²C devices, as well as various sensors, keypads and other
glue as well as interfaces provided via the SCU IPC mechanism (intel_scu_ipc.c)
This patch is a merge of the core elements and relevant fixes from the
Intel development code by Feng, Alek, myself into a single coherent patch
for upstream submission.
It provides the needed infrastructure to register I2C, SPI and platform devices
described by the tables, as well as handlers for some of the hardware already
supported in kernel. The 0.8 firmware also provides GPIO tables.
Devices are created at boot time or if they are SCU dependant at the point an
SCU is discovered. The existing Linux device mechanisms will then handle the
device binding. At an abstract level this is an SFI to Linux device translator.
Device/platform specific setup/glue is in this file. This is done so that the
drivers for the generic I²C and SPI bus devices remain cross platform as they
should.
(Updated from RFC version to correct the emc1403 name used by the firmware
and a wrongly used #define)
