It's the one aberration in v8, the only cpu that
didn't actually have hardware multiply and divide
instructions.

sparc32: drop sun4c support

Machines with sun4c support are very rare these days, and noone
is using them for any practical purposes.
The sun4c support has been know broken for quite some time too.

So rather than trying to keep it up-to-date, lets get rid of it.
This allows us to do some very welcome cleanup of sparc32 support.

Updated the former sun4c specifc nmi (which was also used
for sun4m UP) to be a generic UP NMI.

sparc32,leon: operate on boot-cpu IRQ controller registers

* use boot_cpu_id index to address into the IRQ controller where

Each CPU has a separate set of IRQ controller registers, this
patch makes sure that the boot-cpu registers are used instead
of CPU0's.

sparc32: always define boot_cpu_id

Define boot_cpu_id in single-processor kernels as well. This is
to support architectures which can boot on other than CPU0.

Sam Ravnborg has written the cleanup parts by extracting
boot_cpu_id from smp_32.c into setup_32.c and cleaned up
sun4d_irq.c.

boot_cpu_id was initialized before BSS was cleared in
sun4c_continue_boot, instead boot_cpu_id is set to 0xff to
avoid BSS. If boot_cpu_id is untouched (0xff) by bootup code
it will be overwritten to 0. boot_cpu_id4 is automatically
calculated in common code.
