[PATCH 2/8] clk: qcom: alpha-pll: 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
on the cover letter of this series.

Note that prior to running the Coccinelle,
clk_alpha_pll_postdiv_round_ro_rate() was renamed to
clk_alpha_pll_postdiv_ro_round_rate().
