RTC_LIB is the way to go; the non-RTC_LIB drivers are there only for
backward compatbility.  A grep through the defcconfig files for all
platforms on all architectures finds that by now all have set
CONFIG_RTC_LIB and the remaining users of CONFIG_RTC, CONFIG_JS_RTC,
CONFIG_GEN_RTC, CONFIG_EFI_RTC, CONFIG_DS1302 (which all depend on !RTC_LIB)
are all defconfig files which seem to be slowly bitrotting.

Time to axe !RTC_LIB?  I'm tempted.
