clk: imx: imx6ul: Move csi_sel mux to correct base register
[ Upstream commit 2f9d61869640f732599ec36b984c2b5c46067519 ]
The csi_sel mux register is located in the CCM register base and not the
CCM_ANALOG register base. So move it to the correct position in code.
Otherwise changing the parent of the csi clock can lead to a complete
system failure due to the CCM_ANALOG_PLL_SYS_TOG register being falsely
modified.
Also remove the SET_RATE_PARENT flag since one possible supply for the
csi_sel mux is the system PLL which we don't want to modify.
