Add basic HDR mode support for the svs I3C master driver. Only support for private transfers and does not support sending CCC commands in HDR mode. Key differences: - HDR uses commands (0x00-0x7F for write, 0x80-0xFF for read) to distinguish transfer direction. - HDR read/write commands must be written to FIFO before issuing the I3C address command. The hardware automatically sends the standard CCC command to enter HDR mode. - HDR exit pattern must be sent instead of send a stop after transfer completion. - Read/write data size must be an even number.
