struct pic32_sport::ref_clk is only set, but not read. That means we can
remove it. And when we do so, pic32_enable_clock() and
pic32_disable_clock() are simple wrappers around clk_prepare_enable()
and clk_disable_unprepare() respectively. So we can remove the former
two from the code and replace it by the latter two.
