esp32s2: Fix wakeup fail issue when pd peripheral in lightsleep.

esp32s2: fix wrong deepsleep configuration issue.

1. if RTC_CK8M_ENABLE_WAIT_DEFAULT set to 1, rtc peripherals will not poweron successfully if pd peripherals in light_sleep, the minimum RTC_CK8M_ENABLE_WAIT_DEFAULT is RTC_POWERUP_CYCLES + RTC_WAIT_CYCLES + 2;
2. when goto deepsleep after lightsleep waking up, rtc regulator should not force pu.
