kevin: rk3399: enabling RTC wakeup
Enabled CONFIG_CMD_RTC_ALARM. EC_HOST_EVENT_RTC
is enabled when the rtc_alarm goes off,
alerting the AP to transition from S3->S0.
BUG=chrome-os-partner:52218
BRANCH=None
TEST=rtc_alarm <num> and see event set in ec console
after <num> seconds. Also, check if new bit set
through hostevent command in ec before/after
rtc_alarm goes off.
