[PATCH] drm/rockchip: vop2: move clk-disable into its own function

[Heiko Stuebner]

Right now vop2_enable calls vop2_core_clks_prepare_enable to handle the
vop clocks, but vop2_disable directly disables the clocks.

Not nice from a symmetry point of view and also if we ever need to disable
the clocks elsewhere, this would become a problem, so move clock disable
into its own function as well.
