Currently, HPD(Hot Plug Detection, a module used for detecting
HDMI cable connection) soft debouncing logic implements around
1 sec mechanism to stabilize HPD event detection. In case of
fast HPD connect/disconnect, it is missing a real HPD event.
This change implements a new debouncing logic in driver which
will make sure the first real HPD event is correctly processed
and at the end of debouncing processing, if there is a change
in HPD state, the changed state is also processed. This way we
always process the change of HPD states.

When A2 turns on, queue_rx() is first run from the SMSM thread, and
attempts to allocate 32 2kB-buffers with GFP_KERNEL for DMA transactions.
If the system is low on memory, the allocation could put the thread to
sleep while the memory allocator scavenges for enough memory to satisfy
the request. This is not desired as it stalls a critical system thread
that is communicating with a real-time system.
Instead, use GFP_NOWAIT which will return immediately if no memory is
available for the allocation request so that bam_dmux may handle the
situation gracefully and possibly reschedule the allocations for a later
time.
