The exynos4x12 has different address of GATE_IP_IMAGE reg. We should use
EXYNOS4X12_GATE_IP_IMAGE for g2d gating clocks instead of 4210's reg.
In case of mdma node, We don't use it for any exynos4 chipsets. I think we'll
need to change it to 'none' or leave it on.

Which kernel version is this patch based on? G2D clocks for 4x12 has
already been added by commit 5cd644d837 ("clk: exynos4: Add additional
G2D clocks").
