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.
BUG=b:80501386
TEST=manually flashed into kukui and boots into romstage.

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.

Enable MMU in bootblock for performance, link common code to provide
mtk_mmu_after_dram() to update MMU table in romstage after dram ready,
implement mtk_soc_disable_l2c_sram(), and call
mtk_mmu_disable_l2c_sram() to turn off L2C sram in ramstage.

Using common watchdog timer (WDT) code for reset. Set up watchdog timer
in mtk_wdt_init() to get reset status and disable auto-reboot. Link
common do_hard_reset() to support hard reset.
BUG=b:80501386
BRANCH=none
TEST=both mtk_wdt_init() and do_hard_reset() work on Kukui.
