mediatek/mt8183: Fix RTC initialization flow
1. Fix RTC lpd settings. Rewrite powerkeys after lpd init to enable low power detect function. 2. Rearrange RTC initialization flow. 3. Add return status for rtc_init. 4. Add log if calling pwrap_write or pwrap_read fail. 5. Increase timeout time to resolve unexpected timeout.
