qcacmn: FR65980: Add MLO timestamp support for pktlog

Browse Source 
Whenever firmware receives the sync interrupt, it would
update the MLO offset to the scratch registers. Additionally,
firmware also sends a HTT message.

The values from the HTT message are copied into two structures:
1. into the dp_pdev structure, for monitor mode usage
2. into the scn structure for updating the pktlog header
    A new WDI event is introduced for MLO timestamp sync into
    pktlog header. Host sends the WDI event once it receives
    htt msg and the data gets parsed in the pktlog handler and
    eventually pktlog header gets updated with those values.

Whenever pktlog memory is being filled, the latest value from scn
structure is filled into the pktlog header. Upon receiving a new
HTT message, the value in the scn structure is updated and
subsequently into the pktlog records as well. All the 8 bytes
from the HTT message are required to calculate the MLO timestamp
offset. The calculation of MLO timestamp offset is to be taken
care by the PKTLOG parsing script.
