From: Janusz Krzysztofik jmkrzyszt@gmail.com
The driver, OMAP1 specific, now omits clk_prepare/unprepare() steps, not supported by OMAP1 custom implementation of clock API. However, non-CCF stubs of those functions exist for use on such platforms until converted to CCF.
Update the driver to be compatible with CCF implementation of clock API.
