powerpc: Merge various powermac-related header files.

Except for smu.h, which moved from asm-ppc64 to asm-powerpc, all
of these moved from asm-ppc to asm-powerpc.  In each case the
asm-ppc64 version (if there was one) was just a single line
including the asm-ppc version.

+ *       ASIC registers.
+ *
+ * Implementation note: Currently, none of these functions will block.
+ * However, they may internally protect themselves with a spinlock
+ * for way too long. Be prepared for at least some of these to block
+ * in the future.
+ *
+ * Unless specifically defined, the result code is assumed to be an
+ * error when negative, 0 is the default success result. Some functions
+ * may return additional positive result values.
+ *
+ * To keep implementation simple, all feature calls are assumed to have
+ * the prototype parameters (struct device_node* node, int value).
+ * When either is not used, pass 0.
