The limits were appropriate only for the 2nd set.
FWIW, the channel count 4 for the 2nd set is suspicious as well - at least P17V_PLAYBACK_FIFO_PTR actually has 8 channels, and comments on HCFG2 hint at that as well. But all bitmasks are documented only for 4 channels. Anyway, rectifying that is out of scope for this patch.
