powerpc/mpic: remove unused functions
Drop unused fsl_mpic_primary_get_version(), mpic_set_clk_ratio(),
mpic_set_serial_int().
+ fsl_mpic_primary_get_version() is just a safe wrapper around
fsl_mpic_get_version() for SMP configurations. While the latter is
called explicitly for handling PIC initialization and setting up error
interrupt vector depending on PIC hardware version, the former isn't
used for anything.
+ As for mpic_set_clk_ratio() and mpic_set_serial_int(), they both 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.
