Pull RTC updates from Alexandre Belloni:
 "Two new drivers this cycle and a significant rework of the CMOS driver
  make the bulk of the changes.

  I also carry powerpc changes with the agreement of Michael.

  New drivers:
   - Sunplus SP7021 RTC
   - Nintendo GameCube, Wii and Wii U RTC

  Driver updates:
   - cmos: refactor UIP handling and presence check, fix century
   - rs5c372: offset correction support, report low voltage
   - rv8803: Epson RX8804 support"
