commit 12fd64babaca4dc09d072f63eda76ba44119816a upstream.
There is a clk == NULL check after the switch to check for
unsupported clk types. Since clk is re-assigned in a loop,
this check is useless right now for anything but the first
round. Let's fix this up by assigning clk = NULL in the
loop before the switch statement.

Similar to DCLK_LCDC on RK3328, the DCLK_VOP on RK3228 is typically
parented by the hdmiphy clk and it is expected that the DCLK_VOP and
hdmiphy clk rate are kept in sync.
Use CLK_SET_RATE_PARENT and CLK_SET_RATE_NO_REPARENT flags, same as used
on RK3328, to make full use of all possible supported display modes.

The HCLK_OTG gate control is in CRU_CLKGATE5_CON, not CRU_CLKGATE3_CON.
