[media] media:davinci: clk - {prepare/unprepare} for common clk
As a first step towards migrating davinci platforms to use common clock
framework, replace all instances of clk_enable() with clk_prepare_enable()
and clk_disable() with clk_disable_unprepare().
Also fixes some issues related to clk clean up in the driver
