Add clock controller support for the Sophgo CV1800B, CV1812H and SG2000.

Changed from v7:
1. fix unused variables warnings in patch 3 of v7
2. fix wrong pointer type in patch 3 of v7
3. move the clk_disp_vip_parents variable to the patch 5 to avoid warning

Changed from v6:
1. fix dead lock when setting rate.
2. split the driver patch into several patch for easy reading.

Changed from v5:
1. rebased to mainline master tree
2. add SG2000 clock support.
3. fix document link

Changed from v4:
1. improve code for patch 2
2. remove the already applied bindings

Changed from v3:
1. improve comment of patch 3
2. cleanup the include of patch 2

Changed from v2:
1. remove clock-names from bindings.
2. remove clock-frequency node of DT from previous patch.
3. change some unused clock to bypass mode to avoid unlockable PLL.

Changed from v1:
1. fix license issues.
