Fix setting of a year in m48t08 and m48t02 clocks.
They do not have century bits and setting them
causes the year to overflow (bit 0x80 set).
Problem found by Robert Reif on Sun Sparcstation 20.

Add support for externally mapped ioaddr. This is required on sparc32
as the ioaddr must be mapped with of_ioremap().

Add support for two compatible RTC:
- M48T08 which does not have alarm part,
- M48T08 which does not have alarm part and has
only 2KB of NVRAM
These types covers all Mostek's RTC used in Sun UltraSparc workstations.
Tested on Sun Ultra60 with M48T59 RTC.

Remove element size from the structure m48t59_private as it is used as
local variable for storing temporary value.

This mirrors the of_device_id[] changes done in
fd098316ef ("sparc: Annotate
of_device_id arrays with const or __initdata.")

While doing some easy cleanups on the sparc code I noticed that the
CONFIG_SUN4 code seems to be worse than the rest - there were some
"I don't know how it should work, but the current code definitely cannot
work." places.
And while I have seen people running Linux on machines like a
SPARCstation 5 a few years ago I don't recall having seen sun4
machines, even less ones running Linux.

This thing was a mess, who wrote this junk? :)
Luckily we'll soon have nice generic I2C layer drivers for this PCF
based I2C stuff on sparc64.

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 :-)
