The mmio nvram driver (used by cell only atm) isn't properly parsing
the device-tree, meaning that nvram isn't found correctly on the new
Cell blades. It works ok for old blades where the nvram is at the
root of the device tree but fails on Malta and CAB when it's hanging
off axon. This fixes it by using the proper OF parsing functions.

Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

locking init cleanups:
- convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK()
- convert rwlocks in a similar manner
this patch was generated automatically.
Motivation:
- cleanliness
- lockdep needs control of lock initialization, which the open-coded
variants do not give
- it's also useful for -rt and for lock debugging in general

The nvram code formally known as bpa_nvram.c is rather
generic really, so it is quite likely to be useful to
future boards not based on cell.
This patch puts it into arch/powerpc/sysdev.

The official name for BPA is now CBEA (Cell Broadband
Engine Architecture). This patch renames all occurences
of the term BPA to 'Cell' for easier recognition.

The firmware provides the location and size of the nvram
in the device tree, so it does not really contain any
hardware specific bits and could be used on other
machines as well.
