in genrtc the RTC_* defs should be used only for interface definition,
unlike rtc.c where they are 1:1 with some obscure bits in the rtc chip
and also happen to be the interface..
It would make sense to merge them into <linux/rtc.h>, whether it is
a good idea to do it in 2.4 is another question.
Stuff that is really hw dependent should use different naming (and stay
in asm/rtc.h of course).
