[PATCH 30/41] ARM: OMAP1: Prepare for conversion of OMAP1 clocks to CCF

From: Janusz Krzysztofik <jmkrzyszt@gmail.com>

In preparation for conversion of OMAP1 clocks to common clock framework,
identify arch/arm/mach-omap1 local users of those clocks and update them
to call clk_prepare_enable/clk_disable_unprepare() instead of just
clk_enable/disable(), as required by CCF implementation of clock API.
