sunxi: add modules for AC100 MFD and RTC

Browse Source 
The X-Powers AC100 is a multi-function IC used to provide RTC
and audio codec via RSB (reduced serial bus, an Allwinner-
speciality). On some boards using the A80/A83T SoCs, aside
from the RTC functionality, the RTC is used as a clocksource
for the Ampak WiFi/BT modules.

Add modules for the core MFD support and the RTC.
