Veyron: Add RW_LEGACY and RW_ELOG sections to FMAP

This patch changes the FMAP for Veyron boards to include space for the
event log and legacy firmware section. The event log is not yet
supported in coreboot, but making room for it already doesn't hurt. The
legacy firmware will probably not be shipped with a real binary, but we
still want to provide the feature to users in case they would like to
hack up their own.

All offsets copied straight from Nyan, because I'm lazy and those are
known to be good (at least I hope...).

BRANCH=veyron
BUG=None
TEST=Pressed CTRL+L, confirmed that error message is now "couldn't load
payload" instead of "FMAP section not found". Ran suspend/resume cycle
with mosys_eventlog flag, saw in powerd log that mosys_eventlog calls no
longer failed but 'mosys eventlog list' still doesn't show any events
afterwards. No idea if that's expected...
