This patch implements board reset on the Cheza board. The real board
reset used by the operating system uses the PMIC, but unfortunately the
PMIC needs to be configured right for that to work. The PMIC
configuration currently happens in the Qualcomm blob (QcLib) that is run
from romstage, but vboot needs to be able to reboot during verstage
already. Porting all the PMIC initialization code to run in the
bootblock seems excessive (and at odds with the goal of doing as little
as possible before verification), so we'll just do a little hack and ask
the EC to perform a cold reset instead. For vboot purposes, this should
work just as well.
BUG=b:118501305
TEST=Hacked vboot code to call vboot_reboot(), confirmed that board
reset and came back up as expected.

We didn't have a hard_reset() implementation for these boards. So
select the board_reset() stub for them.

The Cheza board contains a couple of non-standard FMAP sections that
contain per-board calibration data. When flashing new firmware to the
board, care should be taken to copy these sections over so that all
features can still function correctly afterwards. This patch wraps a new
RO_PRESERVE FMAP section around these sections to make them easier to
preserve as a group.

This patch overhauls the Cheza FMAP, removing some sections we don't
seem to need (RW_CDT, the two RW_XBL_BUFFERs, and the second copy of
RW_DDR_TRAINING), and adding new sections we're going to need soon or
should have had anyway (RO_DDR_TRAINING, RO_FSG, RW_LEGACY).
Make more use of implicit offsets and sizes, because we can and because
it should make future adjustments easier.

The romstage main() entry point on arm64 boards is usually in mainboard
code, but there are a handful of lines that are always needed in there
and not really mainboard specific (or chipset specific). We keep arguing
every once in a while that this isn't ideal, so rather than arguing any
longer let's just fix it. This patch moves the main() function into arch
code with callbacks that the platform can hook into. (This approach can
probably be expanded onto other architectures, so when that happens this
file should move into src/lib.)
Tested on Cheza and Kevin. I think the approach is straight-forward
enough that we can take this without testing every board. (Note that in
a few cases, this delays some platform-specific calls until after
console_init() and exception_init()... since these functions don't
really take that long, especially if there is no serial console
configured, I don't expect this to cause any issues.)

This patch makes sure we deassert the USB hub reset pin so the hub will
work with the next board revision that drops the external pull-up.
(Actual USB support comes in a later patch.)
