Series introduce some improvements to drd.c, drd.h and core.c files of cdns3 driver. Except for the first (1/9) patch that removes not needed function, the rest patches make improvements suggested by Dan Carpenter during reviewing CDNSP driver. CDNSP is the next Cadence USBSSP driver which will be upstreamed. The DRD part is similar for both CDNS3 and CDNSP and Greg suggested to merge the similar part of DRD code. As first step I want to merge some improvemnts.
