Add srng pointer register writing history, it is helpful
for debugging srng HP/TP update issue from host side.
(1) if host faced UMAC source ring, record the HP value and timestamp
when host write the register.
(2) if host faced UMAC destination ring, record the TP value and
timestamp when host write the register.

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.

Current implementation of hal_srng_access_start() reads the ring pointer
in the same byte-order as it is written by the target. This results in
byte-order mismatch on a big-endian Host because the WLAN target is
little-endian based. For most of the srngs, the target already takes of
this by converting the ring pointer to the host-order before writing to the
DDR. But for other srngs, the Host needs to handle the endianness
conversions. Add HAL APIs to do the same.
