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.
