powerpc: Hook up rtc-generic, and kill rtc-ppc

PowerPC has been a long time user of the generic RTC abstraction, so hook up
rtc-generic:
  - Create the "rtc-generic" platform device if ppc_md.get_rtc_time is set,
  - Kill rtc-ppc, as rtc-generic offers the same functionality in a more
    generic way, and supports autoloading through udev.
