drm/exynos: prepare FIMD clocks
While migrating to common clock framework (CCF), I found that the FIMD clocks were pulled down by the CCF. If CCF finds any clock(s) which has NOT been claimed by any of the drivers, then such clock(s) are PULLed low by CCF. Calling clk_prepare() for FIMD clocks fixes the issue. This patch also replaces clk_disable() with clk_unprepare() during exit, since clk_prepare() is called in fimd_probe().
