qcacmn: Fix hal_get_srng_ring_id() for Beryllium LMAC rings

For Beryllium LMAC rings, hal_get_srng_ring_id() provides the ring IDs
separately per each LMAC only if that LMAC ring is a destination ring
(This is done to use a common source ring for the DMAC rings).
But the ring IDs for LMAC source rings like DIR_BUF_RX_SRC_DMA_RING are not
being provided separately per LMAC. As a result, these ring IDs in
split-PHY mode are colliding for the 2 LMACs.
Fix this by doing the following.
 - Mark the DMAC common rings within the LMAC rings.
 - Provide ring ID separately per each LMAC if the ring is an LMAC ring
   but not a DMAC common ring.
