Currently if HP/TP register updates are delayed due to delayed reg
write work not getting scheduled, although driver has processed
the ring completely, hardware would see HP/TP delta and fires an
interrupt based on interrupt threshold configuration until the
HP/TP updates reach the hardware.
When system is heavily stressed, this delay in HP/TP updates would
result in IRQ storm further stressing the system which is bad.
Force update HP/TP to the hardware under such scenarios to avoid
this problem.
Currently doing this just for CE DST SRNGs, this can be scaled to
other SRNGs on need.

when host write the register.
(2) if host faced UMAC destination ring, record the TP value and
timestamp when host write the register.

Below signature is seen on sdxpinn when HOST reads IPA TX
doorbell address, which leads to HLOS crash.
Internal error: synchronous external abort: 96000010
Indeed IPA TX doorbell address is write-only. Behaviors
on such read access violation is arch-dependent. On
certains platforms, such violation is ignored but read
returns 0.
Hence remove the read access to IPA TX doorbell address
in hal_srng_dst_init_hp() to avoid arch-dependent
behavior.

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.

For reo_cmd ring, in current implementation, we call hal_srng_access_end
in case a descriptor is not available before baling out. This may cause
a write to the shadow register for the reo_cmd ring. In case we are in
the middle of WOW, this can be problematic.
Modify existing implementation to use hal_srng_access_end_reap, which
will not schedule a write to the register and simply return.
