Currently on WCN6450 which is based on IPCI, there is a problem
in re-enabling the IRQs while firmware recovery is in progress.
While processing the CE IRQs, if there’s an active recovery
happening in the host (due to FW assert), we are leaving the IRQs
disabled in the kernel.
Fix this by refactoring the code such that hif_irq_disable() is
called only when there is no active recovery.

For ipci interface platforms, currently RTPM resume is
requested from CE interrupt handler even when suspend
is in progress. But ideally we should request resume
only RTPM state is in suspended, since as part of suspend
sequence also we will get CE WOW events and this should
not trigger resume.
Fix this by requesting resume from CE interrupt handler
only when driver state is suspended.

In current case when RRI on DDR feature is enabled then host
programs CE control register, but there is chance of F.W also
programming the CE control register around same time this leads
to race and chance of either host/F.W value getting over written.
So to avoid this while programming the CE control register for
RRI on DDR enablement, update it with F.W programming value also
i.e DMA length. So if incase register value over written due to
race proper value will be updated to register either by host/F.W.

Currently, the size of target to host CE pipe for HTT RX communication
for WCN6750 is 512. The data that we receive on this pipe is not very

Regarding to the platform suspend, generally the hif_bus_suspend() will
disable the CE irqs, however the irq is shared in the single MSI case,
so the MHI irq is disabled as well which cause no MHI ring event notified
in the following pci bus suspend.
The fix is to bypass hif apps irqs handle for single MSI case during
suspend-resume stage.
