Currently for WCN6450, driver is updating the CE write index offset
used for CE register updates even for the CE rings that are firmware
only rings. This is resulting in a boot time WARN_ON.
Do not setup write index offset for CE rings that are used only by
the target firmware to avoid this early on boot time WARN_ON.

Unlike lithium family, batch interrupt thresholds for Rhine targets
are not based on the entry size (descriptor size in dwords); Instead
the configuration should be a simple integer value. If interrupt has
to be raised after every copy transaction then batch counter threshold
shall be set to 1, so on and so forth.

Currently, buffers attached to fastpath CEs are not being allocated
from WBUFF. Since the buffers attached to the fastpath CEs are
re-usable in nature, allocating such buffers from WBUFF will have
added benefits like allocating from custom page frag cache which
reduces the memory used by the RX buffers.
Therefore, allocate RX buffers for fastpath CEs from WBUFF module.

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.
