From: Janusz Krzysztofik <jmkrzyszt@xxxxxxxxx>
OMAP1 LCDC drivers now omit 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 drivers to be compatible with CCF implementation of clock API.
