rtc: Allow RTC_DRV_CMOS to be used on SPARC.
Add Sparc to the Kconfig depends list.
Add __sparc___ to address_sparc = 128 ifdef.
Finally, don't be concerned about 24-hour BCD mode support if the RTC
doesn't have a valid IRQ. We won't even use the alarm code in this
case and the Sparc RTCs have this limitation.
