Currently there is no Kconfig symbol to indicate that we want nvram
support on 64-bit kernels; it's assumed we always want it, so make
the powermac setup code always initialize the pmac nvram code if
64-bit.

* Removed of_show_percpuinfo and just report CPU frequency in generic
show_cpuinfo code.
* Killed OCP and PPC_SYS related code which doesn't belong in the
merge tree

Old powermacs have a number of differences from current machines:
- there is no interrupt tree in the device tree, just interrupt
or AAPL,interrupt properties
- the chosen node in the device tree is called /chosen@0
- the OF claim method doesn't map the memory, so we have to do
an explicit map call as well
- there is no /chosen/cpu property on SMP machines
- the NVRAM isn't structured as a set of partitions.
This adapts the merged powermac support code to cope with these
issues.

This brings in a lot of changes from arch/ppc64/kernel/pmac_*.c to
arch/powerpc/platforms/powermac/*.c and makes various minor tweaks
elsewhere. On the powermac we now initialize ppc_md by copying
the whole pmac_md structure into it, which required some changes in
the ordering of initializations of individual fields of it.

I missed a few places where ppc code was still assuming that the
ppc_md.show_[per]cpuinfo functions returned int.

A few things change for consistency between ppc32 and ppc64:
idle functions return void; *_get_boot_time functions return
unsigned long (i.e. time_t) rather than filling in a struct rtc_time
(since that's useful to the callers and easier for pmac to
generate); *_get_rtc_time and *_set_rtc_time functions take
a struct rtc_time; irq_canonicalize is gone; nvram_sync returns
void.

This makes platform code use the smp_ops variable directly instead
of ppc_md.smp_ops, removes the two unused `data' and `wait' arguments
from the *_message_pass() functions, and removes the call to the
never-implemented smp_ops->space_timers() function.

Since the files are now in arch/powerpc/platforms/powermac, the
pmac_ prefix that they had is redundant.
