ENGR00243315-3 MXC V4L2 Capture:Remove unnecessary mclk setting
commit f8e1a3bb62eecf93a31a51c4dbe08a0214fa1d57 added a hard
coding for csi_parma.mclk setting to 27MHz. The comment added by
that commit is totally wrong by telling that csi_param.mclk
would be a kind of 'pixel clock' set in 'csi_data_dest' register.
This patch removes the unnecessary mclk setting for csi_param.mclk
variable, since it is only valid for CSI test mode.
