ddr: altera: Internal scc_mgr_apply_group_all_out_delay_add() cleanup part 2

Clean the DQS and OCT parts of the function, clean up the chopped
formatting strings in debug_cond() and slightly improve the code.
Zap group_bgn argument as it is used only in debug messages. Document
the function using kerneldoc. No functional change.
