misc: xilinx_sdfec: Add ability to get/set config
- Add capability to get SD-FEC config data using ioctl XSDFEC_GET_CONFIG. - Add capability to set SD-FEC data order using ioctl SDFEC_SET_ORDER. - Add capability to set SD-FEC bypass option using ioctl XSDFEC_SET_BYPASS. - Add capability to set SD-FEC active state using ioctl XSDFEC_IS_ACTIVE.
