clk: samsung: exynos850: Implement CMU_G3D domain
CMU_G3D clock domain provides clocks for Mali-G52 GPU and bus clocks for
BLK_G3D.
This patch adds next clocks:
- bus clocks in CMU_TOP for CMU_G3D
- all internal CMU_G3D clocks
- leaf clocks for GPU, TZPC (TrustZone Protection Controller) and
SysReg
G3D_CMU_G3D clock was marked as CLK_IGNORE_UNUSED, as system hangs on
boot otherwise.
