oak: Clean up CONFIG_PMIC_FW_LONG_PRESS_TIMER related codes

CONFIG_PMIC_FW_LONG_PRESS_TIMER was ported long time ago from
Tegra, but the codes are actually not used and erroneous.
It might wrongly trigger set_pmic_pwron(0), and turn off
PMIC power accidentally. This causes POWER_GOOD lost and
power state will go back to S5 during boot up.

Clean up the codes by referencing check_for_power_off_event()
of Rockchip.

BRANCH=none
BUG=none
TEST=bootup and press power button quickly right after we are in S0.
Bootup should still complete normally.
