mediatek/mt8183: Add option MT8183_MINIMIZE_BOOTBLOCK

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 option MT8183_MINIMIZE_BOOTBLOCK in Kconfig. When
enabled, initializations that be can postponed in bootblock will be
removed.
