In preparation of support of inline static calls on powerpc, provide
trampoline address when updating sites, so that when the destination
function is too far for a direct function call, the call site is
patched with a call to the trampoline.

Looks like you don't really have an alternative to
of_mm_gpiochip_add_data(), you are replacing one single line by 11 new
ones, and
reset() was the only caller of dpmcp_reset().
Remove it.
