ddr: altera: Clean up rw_mgr_mem_calibrate_vfifo_find_dqs_en_phase_sweep_dq_in_delay() part 3

Replace at least one of the loops in this function with call of a
standard function call instead of the ad-hoc implementation. The
other one cannot be replaced, since the delay is incremented for
each group.
