it83xx: force filling cache if the last two 4KB blocks of 512KB flash are modified
After immu reset, we will fill the immu cache with 8KB data
that are outside address 0x7e000 ~ 0x7ffff.
When CPU tries to fetch contents from address 0x7e000 ~ 0x7ffff,
immu will re-fetch the missing contents inside 0x7e000 ~ 0x7ffff.
BUG=b:111808417, b:119799561
BRANCH=none
TEST=use console "flasherase" and "flashwrite" commands to erase/write
last two 4KB blocks(0x7e000 ~ 0x7ffff), no error message occurred.
