The asm-generic/rtc.h header can now be included by
architectures that provide their own set_rtc_time/get_rtc_time
macros, letting us remove most of the common contents in
the powerpc implementation.

parisc in this case.

Actually, after the comment about just removing the gen_rtc driver
in the long run, I checked again and found that PARISC unconditionally
selects RTC_CLASS, so this driver can't even be built here.
We should just remove the header and drop PARISC from the list.

If we also drop m68k, that just leaves powerpc.

I've just checked Debian's unofficial linux-image-4.5.0-1-m68k_4.5.1-1_m68k,
and it also enables RTC_CLASS and CONFIG_RTC_DRV_GENERIC, so gen_rtc
can be dropped on m68k for sure.

Ok, excellent. I'll try to rework the series then to completely eliminate
the driver (or leaving it ppc-only).
