clk: imx: imx6ul: Fix csi clk gate register
According to the imx6ul Reference Manual the csi clk gate register is CCM_CCGR3 (offset 0x74) bit 0/1. For the imx6ull on the other hand the Reference Manual lists register CCM_CCGR2 (offset 0x70) bit 2/3 as the csi clk gate which is the current setting. Tests have shown though that the correct csi clk gate register for the imx6ull is actually CCM_CCGR3 bit 0/1 as well. Thus set the correct register for both platforms.
