f1eaf16a9e powerpc/cpm1: Fix race condition in CPM1 GPIO library.
The CPM1 GPIO library code uses the non thread-safe clrbits32/setbits32
macros. This patch protects them with a spinlock.

Based on the CPM2 patch from Laurent Pinchart <laurentp@cse-semaphore.com>,
commit 639d64456e.

19fc65b525 powerpc: Fix irq_alloc_host() reference counting and callers
When I changed irq_alloc_host() to take an of_node
(52964f87c6: "Add an optional
device_node pointer to the irq_host"), I botched the reference
counting semantics.

Stephen pointed out that it's irq_alloc_host()'s business if
it needs to take an additional reference to the device_node,
the caller shouldn't need to care.

3dd82a1ea7 [POWERPC] CPM: Always use new binding.
The kconfig entry can go away once arch/ppc and references to the config in
drivers are removed.

b5677d848c [POWERPC] CPM: Rename commproc to cpm1 and cpm2_common.c to cpm2.c
Rename commproc.[ch] to cpm1.[ch] to be more consistent with cpm2. Also
rename cpm2_common.c to cpm2.c as suggested by Scott Wood. Adjust the
includes accordingly.
