chip/it8xxx2: Don't let internal flash go into deep power down mode
We got an issue on IT83202BX that flash won't be able to wake up
correctly in EC low power mode when WRST# is asserted.
This issue might cause cold reset failure so we made this change
to fix it.
BUG=none
BRANCH=none
TEST=hibernate EC and then press servo board's COLD_RST_L to reset EC.
EC reboots.
