When Intel MID finds a match between SFI table from FW and registered
SFI devices, it will always register a device regardless the platform
code was successful or not.
This patch adds an extra option for platform code to return error code
and abort device registration on SFI table parsing.
This patch does not contain any functional changes for current intel
mid platform code.

As Intel rolling out more SoC's after Moorestown, we need to
re-structure the code in a way that is backward compatible and easy to
expand. This patch implements a flexible way to support multiple boards
and devices.
This patch does not add any new functional support. It just refactors
the existing code to increase the modularity and decrease the code
duplication for supporting multiple soc's and boards.
Currently intel-mid.c has both board and soc related code in one file.
This patch moves the board related code to new files and let linker
script to create SFI devite table following this:
1. Move the SFI device specific code to
arch/x86/platform/intel-mid/device-libs/platform_<device>.*
A new device file is added for every supported device. This code will
get conditionally compiled by using corresponding device driver
CONFIG option.
2. Move the device_ids location to .x86_intel_mid_dev.init section by
using new sfi_device() macro.
This patch was based on previous code from Sathyanarayanan Kuppuswamy.

Intel mid sfi code doesn't need struct devs_id.get_platform_data != NULL.
If the callback is not set, just assume there is no platform_data.

Moved SFI specific parsing/handling code to sfi.c. This will enable us
to reuse our intel-mid code for platforms that supports firmware
interfaces other than SFI (like ACPI).
