Since we move mtk_mmu_init() from bootblock to decompressor, we don't
need to build mmu_opertations.c in bootblock and we don't need to
include <soc/mmu_operations.h> in bootblock.c.

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.
A fully functional bootblock (that can boot into verstage or romstage)
is about 38000 bytes. If self decompression (CONFIG_COMPRESS_BOOTBLOCK)
is enabled, only 25088 (66%) bytes are needed.
Inspired from crosreview.com/1070018.
