mediatek/mt8183: Move some initialization into mt8183_early_init
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 adds a new function mt8183_early_init, which includes all
initializations that should be done in early stages. All mainboards
using MT8183 should manually call it in either bootblock or verstage.
BRANCH=none
BUG=b:120588396
TEST=manually boot into kernel
