[ Upstream commit 21926d466e3a4f35c2536244d1d56512cc81a0a9 ]

Currently video driver is voting after clk enable and un voting
before clk disable. This is incorrect, video driver should vote
before clk enable and unvote after clk disable.

Corrected this by changing the order of clk enable and clk disable.
