char/rtc: replace blacklist with whitelist
Every new architecture has to add itself to the growing list of those that do not support the legacy PC RTC driver. This replaces the long list of architectures that don't support it with a shorter list of those that do. The list is taken from those architectures that have a non-empty asm/mc146818rtc.h header file and were not explicitly blacklisted or select RTC_LIB. Alpha and Loongson64 can already choose between this driver and an rtc-class based one. mn10300 is actually the only architecture now that still requires this driver, and that should be fairly easy to change to use rtc-cmos if we want to kill off rtc.ko for good.
