Store the last MDSS IRQ status value to help identify the source
of any erroneous IRQs that might cause an IRQ storm. Also, check
return codes on IRQ mapping or handling and report any unhandled
IRQs to the IRQ system.

Take the callback spinlock before checking whether the callback
table list is empty. This resolves a race condition where the
callback list could be empty during the servicing of an
interrupt.

Update the sde_dbg_dump function to only dump event log
entries up to the time the dump is initiated, and increase
the number of recorded event log entries.
This places a limit on the total number of entries that are
output to the dmesg log even if more entries would have been
added while the dump is executing (e.g., interrupt events),
while still allowing the extra events to be recorded properly.

This change adds debugfs nodes for debugging underruns,
after this change following commands are supported:
1. To enable the underrun ftrace:
echo 1 > /d/tracing/events/sde/sde_encoder_underrun/enable
2. To enable feature that disables the ftraces once the
underrun happens:
echo 1 > /d/dri/0/debug/dbg_ctrl
3. To enable the panic in the device when underrun happens:
echo 2 > /d/dri/0/debug/dbg_ctrl
4. To enable both of the above options:
echo 3 > /d/dri/0/debug/dbg_ctrl

For MI2S shutdown, if clock disable fails,
do not increment clock reference. Otherwise,
next time when startup is called, clock enable will not
be called again, so use case will not work.

In cleanup_stats(), a freed memory pointer pos might be accessed for
list traversal. Switch to using _safe() variant of the list API to
prevent undefined accesses.
