Change subject: soc/mediatek: Flush cache before triggering EC reset

soc/mediatek: Flush cache before triggering EC reset

There will be no log in cbmem if we trigger ec reset on bootblock
stage. Therefore, call dcache_clean_all() before triggering ec
reset to flush cache to store logs on cbmem.

BUG=b:207743045
TEST=show logs on cbmem
