fsp_baytrail: Add the FSP version of Intel's Bay Trail-I chip

While similar to the Bay Trail-M/D code based on the MRC, there are
many differences as well:
- Obviously, uses the FSP instead of the MRC binaries.
- FSP does additional hardware setup, so coreboot doesn't need to.
- Different microcode & microcode loading method
- Uses the cache_as_ram.inc from the FSP Driver
- Various other changes in support of the FSP
Additional changes that don't have to to with the FSP vs MRC:
- Updated IRQ Routing
- Different FADT implementation.
This was validated with FSP:
