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.

This patch adds init memory poisoning.  It looks like
totalram_pages was not updated properly in free_initrd_mem
so I fixed that as well.

Use rtc subsystem for sparc32 architecture.
Actually, only one driver is needed: m48t59
as it supports the most common clocks on sparc32
machines: m48t08 and m48t02.

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.

Make sparc64 refrain from clearing a given to-be-offlined CPU's bit in the
cpu_online_mask until it has processed pending irqs.  This change
prevents other CPUs from being blindsided by an apparently offline CPU
nevertheless changing globally visible state.

When I switched sparc64 over to the generic helpers for
smp_call_function(), I didn't convert the dinky call_lock
we had.

Use ipi_call_lock() and ipi_call_unlock().

The device nodes that sit above 'esp' and 'le' on SBUS lack a 'ranges'
property, but we should pass the translation up to the parent node so
that the SBUS level ranges get applied.

Three main things:

1) Make prober an arch initcall instead of using hard-coded invocation
   from paging_init()

2) Shrink table size, the fpu ident stuff was never used.

3) Use named struct initialized in table.

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 driver is now limited to just doing the basic clock board and FHC
chip initialization and registering the platform devices for the
per-board LEDs, which are driven by the new LEDS_STARFIRE driver.

The IRQ register handling is already confined purely to the device
tree code.
