Batch buffer will be created through dsb-reg-write function which can have
single/multiple request based on usecase and once the buffer is ready

the registers will be updated simultaneously.
v1: Initial version.
v2: Optimized code few places. (Chris)
v3: USed DRM_ERROR for dsb head/tail programming failure. (Shashank)
v4: reset ins_start_offset after commit. (Jani)
