[PATCH 4/4] powerpc/mpic: remove unused functions

[Arseny Solokha]

Drop unused mpic_set_clk_ratio() and mpic_set_serial_int().

Both functions are almost nine years old[1] but still have no chance
to be called even from out-of-tree modules because they both are __init
and of course aren't exported.
