MIPS: Alchemy: convert from round_rate() to determine_rate() 

The round_rate() clk ops is deprecated, so migrate this driver from
round_rate() to determine_rate() using the Coccinelle semantic patch
appended to the "under-the-cut" portion of the patch.

Note that prior to running Coccinelle, alchemy_clk_aux_roundr() was
renamed to alchemy_clk_aux_round_rate(). A few minor style cleanups
were also done by hand.
