Existing solution to reserve the memory region for CNSS ramdump
collection has it's own limitations because of reserving the
memory region for each platforms even before CNSS driver is
probed. Add implementation to allocate the required memory for
CNSS ramdump using dma_alloc_coherent API and update the physical
address in dump table so that tools can find the starting address
of the CNSS ramdump in the crash dump.

A freemem list entry maybe truncated/deleted even if it doesn't
overlap with a new buffer, for example, if the new buffer is entirely
to the left or right of the entry. Fix the conditional logic so
that an entry may be truncated/deleted only if it overlaps with
the new buffer.

We call msm_iommu_bus_register only when legacy

the driver is disabled, we never register our

end up with NULL pointer exception if clients try
to call iommu_present with this dummy bus.
Put a NULL pointer check to ensure we don't end

When a system is entering RPM assisted sleep, the NOACK messages are not
accounted in preventing such sleep modes as no driver is waiting on it. In
such scenarios, some active messages could still be in the Apps RX buffer
which reduces the number of outstanding sleep messages.
Fix by accounting for NOACK messages while flushing sleep set requests and
ensuring that they are read before sending any Sleep set requests.

The current implementation would check for the parent rate and decide the
handoff state of the clock, which is not true for mux clocks. With this
logic the function returns 'enabled' even when the clock downstream of this
clock is disabled. The handoff code will unnecessarily enable the current
parent of this clock.
If this function always returns 'disabled' and a clock downstream is on,
the clock handoff code will bump up the ref count for this clock and its
current parent as necessary. The clocks without an actual HW gate can
always return handoff disabled.
