sparc64: Check for RTC class device in update_persistent_clock().
As we convert the various by-hand sparc64 RTC drivers to use the
generic RTC framework and drivers, we need to keep the NTP
set_rtc_mmss() support via update_persistent_clock() working.
In the end, after all the RTC device cases are converted, this
local set_rtc_mmss() function will be deleted.

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.
