powerpc/kprobes: Replace ppc_optinsn by common optinsn
Commit 51c9c0843993 ("powerpc/kprobes: Implement Optprobes")
implemented a powerpc specific version of optinsn in order
to workaround the 32Mb limitation for direct branches.
Instead of implementing a dedicated powerpc version, use the
common optinsn and override the allocation and freeing functions.
This also indirectly remove the CLANG warning about
is_kprobe_ppc_optinsn_slot() not being use, and the powerpc will
now benefit from commit 5b485629ba0d ("kprobes, extable: Identify
kprobes trampolines as kernel text area")
