The DU CRTC driver does not support distinguishing between a hardware index, and a software (CRTC) index in the event that a DU channel might not be populated by the hardware. Support this by adapting the rcar_du_device_info structure to store a bitmask of available channels rather than a count of CRTCs. The count can then be obtained by determining the hamming weight of the bitmask. This allows the rcar_du_crtc_create() function to distinguish between both index types, and non-populated DU channels will be skipped without leaving a gap in the software CRTC indexes.
