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.
