common: qixis: make the qixis compatible with new soc

Browse Source 
This driver needs modification to work with new soc,
like ls1028, since bitmap of RCFG is changed to
RESV[7:5] LIVE[4] WDEN[3] RESV[2:1] GO[0]
   000      1       0        00      0

Also the RCW location is moved to only dutcfg0.
RESV[7:4] RCWSRC[3:0]
   1111   configurable

Following commands are functional now
qixis_reset
qixis_reset sd
qixis_reset qspi
qixis_reset emmc
