The idea is that they stay low unless we know that we booted from SPI
flash. As this code runs in SPI flash - it is ok to turn these rails
on as soon as possible, and pp3000 rail it is essential for UART to
work.
Kevin rev1 and Gru designs are going to be using these pins to
control these rails. Kevin rev1 had those GPIO pins routed to two
chip enable signals, it is save to assert them high.

Gru is the common name of a set of coreboot boards, each of them has
the config option BOARD_GOOGLE_GRU enabled. Now we need to add the
actual board called Gru to the set. Let's rename the common config
option to BOARD_GOOGLE_GRU_COMMON and use BOARD_GOOGLE_GRU for the
actual board.

BUG=none
TEST=with corresponding depthcharge and configuration space changes it
is possible to build the Gru board which boots the kernel using
the proper compatibility string of google,gru-rev0

The Board ID on the Gru family of boards is determined by reading the
voltage from a resistor divider, each hardware revision is supposed to
have a unique resistor ratio, which allows to distinctly tell between
different Board ID.
While the long time approach to mapping resistor ratios (and voltages)
into Board ID remains under discussion, we know for sure the values
for Proto 1 and Proto 2. Let's just use them for now.
Since Board ID can be queried multiple times during boot, ideally it
should be read once and placed in the coreboot table to be available
to all coreboot stages. For now we just cache it so that at least
during the same stage the ADC has to run only once.
BRANCH=None
BUG=chrome-os-partner:51537
TEST=verified that the voltage reading on Proto 1 is as expected, and
Board ID 0 is reported.

To avoid diverging too much on an actively developed code base, keep
the changes to a separate commit that can be downstreamed more easily:
- removed unused includes
- gave kevin board a "Kevin" part number
- marked RW_LEGACY as CBFS region (to follow up upstream changes)
- moved romstage entry point to SoC code (instead of encouraging
per-board copy pasta)
