1. Add hif_force_wake_request API to wake the
mhi and umac before reading/writing the memory region
greater than BAR+4K.
2. Add hif_force_wake_release API to release the
PCIE_PCIE_LOCAL_REG_PCIE_SOC_WAKE_PCIE_LOCAL_REG so the
umac can power collapse again at a later point of time.
3. Add pci stats to dump the force wake status.

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.

Printing ring stats from requesting txrx stats needs access PCIe link

be called right after sending the packet.

Mailbox based devices do not use the SDIO abstraction layer.
So, devices like QCA6174, QCA9379 etc are to interface with
the SDIO stack directly, even if the CNSS wrappers are used.
ADMA based devices use the SDIO abstraction layer. So, devices
like QCN7605 do not interface with the SDIO stack directly.

When the wlan driver is suspending, the last thing it does is check to
see if the firmware has indicated a wakeup during the suspend process.
This is done by checking the initial wakeup flag, which is set when a
specific copy engine payload is received from firmware. For the new
dedicated wake MSI, only the wake signal is received, no payload. When
the wake MSI is toggled, set the initial wakeup flag to prevent race
conditions during the suspend process.
