parisc: Enable ARCH_HAS_STRICT_MODULE_RWX

Browse Source 
commit 0a1355db36718178becd2bfe728a023933d73123 upstream.

Fix a boot crash on a c8000 machine as reported by Dave.  Basically it changes
patch_map() to return an alias mapping to the to-be-patched code in order to
prevent writing to write-protected memory.
