Subject: [PATCH 2/3] ARM: OMAP2+: clock: 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.

The change to virt_prcm_set_ops had to be made manually.
