google/kukui: Enable EC_GOOGLE_CHROMEEC_AP_WATCHDOG_FLAG

Kukui AP doesn't remember if the last AP reset was due to AP watchdog.
We need to enable EC_GOOGLE_CHROMEEC_AP_WATCHDOG_FLAG so that it will
query the reset reason from EC during watchdog initialization.

Besides, we should set BOOTBLOCK_EN_L before mtk_wdt_init so that we can
communicate with EC at the time.

BUG=b:109900671,b:118654976
BRANCH=none
TEST=1. run 'mosys eventlog clear; stop daisydog; echo > /dev/watchdog'
     2. wait for watchdog reset
     3. see 'WDT: Last reset was hardware watchdog' in AP console
     4. check 'mosys eventlog list | grep watchdog'
