powerpc/p2041: configure the CPLD lane_mux according to RCW
Lane muxing on p2041 is controlled by a reg in CPLD, offset of this reg is 0xc, CPLD supports SATA by default, we should re-configure the lane muxing according to RCW, which indicates what SerDes protocol it is running. Default lane muxing map is as below: Lane G on bank1 routes to SGMII, controlled by bit 1 of the reg; Lane A on bank2 routes to AURORA, controlled by bit 0 of the reg; Lane C/D on bank2 routes to SATA0 and SATA1, controlled by bit 2 and bit 3 respectively. Default value of these bits for lane muxing is '1', we should set or clear these bits accoring to RCW.
