This also cleans up a lot of crud in this driver:

1) Don't touch the BBC regs, just leave the watchdog trigger
   behavior whatever the firmware programmed it to.

2) Use WATCHDOG_MINOR instead of hardcoded and not properly
   allocated RIOWD_MINOR.

Hey, I haven't touched it since I wrote it years ago :-)

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.

In order to make this week I also had to add an include
of linux/dma-mapping.h to asm/pci_32.h because drivers/pci/pci.c
really depends upon getting this header somehow.
