parisc: Allow live-patching of __meminit functions
commit d19a12906e5e558c0f6b6cfece7b7caf1012ef95 upstream.
When making the text sections writeable with set_kernel_text_rw(1),
include all text sections including those in the __init section.
Otherwise functions marked with __meminit will stay read-only.
