google/kukui: Move some initialization from bootblock to verstage
MT8183 only allows booting from eMMC, so we have to do eMMC emulation
from an external source, for example EC, which makes the size of
bootblock very important.
This CL moves some initialization steps from bootblock to verstage. This
will save us about 2700 bytes (before compression) / 1024 bytes (after
LZ4 compression) in bootblock. In case of CONFIG_VBOOT is disabled,
these initialization steps will be done in romstage.
BRANCH=none
BUG=b:120588396
TEST=manually boot into kernel
