3. Provide header guards and prototypes in superio romstage support.

Bay Trail-I Platform – Bayley Bay-I Customer Reference Board
The Bayley Bay CRB-I is a dual-channel DDR3L SO-DIMM non-ECC platform.
It is designed to support the Bay Trail-I SoC.
This implementation uses the Intel FSP (Vist the Intel FSP
website for details on FSP architecture and support).
This code does not currently support S3. All other features and IO
ports are functional. Booted on Ubuntu 14.04, Mint 16,
Fedora 20 with SeaBIOS payload. Memtest86, FWTS, and
other tests pass.
Notes:
- Generates a 2MB binary to be flashed to the upper 2MB of the ROM,
to preserve the existing Intel Flash Descriptor & TXE binary.
- Tested with B0 & B3 Baytrail I parts
Board support page will be updated on acceptance.

The PCI Specification states that devices that implement
a bridge and a secondary bus must swizzle (rotate) the
interrupt pins according to the table below:
Child Dev # Child PIN Parent PIN
0,4,8,12... A/B/C/D A/B/C/D
1,5,9,13... A/B/C/D B/C/D/A
2,6,10,14.. A/B/C/D C/D/A/B
3,7,11,15.. A/B/C/D D/A/B/C
Which is also described by this equation:
PIN_parent = (Pin_child + Dev_child) % 4
When a device is found and its bus number is greater than 0,
it is on a bridge and needs to be swizzled. Following the
string of parents up to the root bus and swizzling as we go
gives us the desired swizzling result. When BIOS_SPEW is
defined, it will print out each step of the swizzling process.

- 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.

Convert dependent board to generic winbond serial init. Note the clock
function is actually invalid since it never enters into PNP config mode
to twiddle the register. Further, 48MHz is the default (page 9 of
data-sheet) and so romstage.c need not do anything to the clock rate
hence why it presumably works with this invalid function.

The ROM content (CBFS content) captured with
cbfstool build/coreboot.rom print
is useful for two reasons.
1. With the used configuration for the build in `.config`, it can be
compared how the size for romstage and ramstage change over time. To
make that reproducible the used toolchain should also be stored
somewhere in the future.
2. With the CBFS content the time stamps can be better interpreted.
For example, the size of the payload file is needed to interpret the
time stamp for loading the payload.
