This commit always selects COLLECT_TIMESTAMPS and starts
tracking TSC values from the early stages of bootblock.
The initial timestamp value is saved in mm0 and mm1 while
in bootlbock. This approach works because romcc is not configured
to use mmx registers for its compilation.
Additionally, the romstage api with the mainboard was changed to
always pass around a pointer to a romstage_params structure as the
timestamps are saved in there until ram is up.
BUG=chrome-os-partner:22873
BRANCH=None
TEST=Built and booted with added code to print out timestamps at
end of ramstage. Everything looks legit.

During ramstage, call mainboard_get_gpios to get initial GPIO configuration
from the mainboard code, then initialize GPIOs as requested.

TEST=Manual. Using bayleybay GPIO table, set UART GPIOs to 'function 1',
and verify UART still works after GPIO configuration. Also, verify
legacy GPIO config is functional by toggling test pin.

This completes the improvements to the ELF file parsing code. We can
now parse section headers too, across all 4 combinations of word size
and endianness. I had hoped to completely remove the use of htonl
until I found it in cbfs_image.c. That's a battle for another day.
There's now a handy macro to create magic numbers in host byte order.
I'm using it for all the PAYLOAD_SEGMENT_* constants and maybe
we can use it for the others too, but this is sensitive code and
I'd rather change one thing at a time.
To maximize the ease of use for users, elf parsing is accomplished with
just one function:
int
elf_headers(const struct buffer *pinput,
Elf64_Ehdr *ehdr,
Elf64_Phdr **pphdr,
Elf64_Shdr **pshdr)
which requires the ehdr and pphdr pointers to be non-NULL, but allows
the pshdr to be NULL. If pshdr is NULL, the code will not try to read
in section headers.
To satisfy our powerful scripts, I had to remove the ^M from an unrelated
microcode file.

The pattrs structure is intended for the supporting coreboot
code to reference instead of going back to the source of
the values (msrs, cpuid, etc). It essentially serves as a global
structure for collecting attributes about the platform/processor.
Additionally, the implementation provides a point during boot to
hoook work before device enumeration/initialization by providing
a init() function to soc_intel_baytrail_ops that is called before
device work in the boot state machine.
