bde6d309df x86: Change MMIO addr in readN(addr)/writeN(addr, val) to pointer
On x86, change the type of the address parameter in
read8()/read16/read32()/write8()/write16()/write32() to be a
pointer, instead of unsigned long.

375e6ce4ae intel/fsp_baytrail: Clear the GNVS area prior to filling
Zero out the GNVS area so that uninitialized portions are defined.

Tests using Microsoft Windows (XP/7/8) gave a bluescreen bugcheck: A5
(ACPI_BIOS_ERROR) with the first parameter (0x00001000)
(ACPI_BIOS_USING_OS_MEMORY). Some ACPI enumerated devices use the
GNVS area to define whether they're enabled and their MMIO regions.
On my custom baytrail-based board and build, these devices were
disabled but GNVS had uninitialized data indicating the devices
were enabled with improper MMIO regions.

Should investigate further to see where the GNVS device values are
set if enabled and make sure they're set to valid values even when
the devices are disabled via the mainboard/devicetree.cb.

433659ad1e 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:
