In IRQ storm scenario, the events are logged to hif
event desc history even though the SRNG is empty
resulting in overwriting of older entries useful for
debugging.
Fix is to avoid recording hif events if the SRNG is
empty in IRQ storm scenario.

UMAC reo full condition is seen in slub debug builds in case of
DL throughput traffic. This is due to host process only 64 packets
per NAPI schedule in case of slub debug builds where in case of
perf builds budget is of scale 4 times. Also the time between two
napi schedules is in order of milliseconds which accounts for the
delay of host reo ring processing. So increase the napi budget
scale to 3 times which make sures host process enough packets per
napi schedule.

Add runtime pm apis to record last busy mark set by data path
during dp rx process.
Currently for mcl in some scenerios runtime sync suspend is issued
which puts the link in low power state with out waiting for link
inactivity timeout. This leads to throughput degradation in case of
rx direction as in rx processing data path extends the timer by marking
last busy to avoid immediate runtime suspend. But runtime sync suspend
does not take in to account of the link idle timeout value before
suspending the link. So using this apis, before issuing runtime sync
suspend check the duration since last busy mark by data path rx process.
If the duration is less than run time delay just do runtime put.
