Michael Ellerman 15efd61fa7 powerpc/io: Unhook MMIO accessors
Now that PPC_INDIRECT_MMIO is removed, it's not possible/necessary
to hook any of the "memory" accessors, so turn them back into regular
static inlines, and restrict the hooking mechanism to the "pio"
accessors only.

Move the #defines that signal each routine is implemented next to the
implementation, and update the out-of-date comment.
