Don't process any attention requests after hpd off. During automation
tests, scripts are doing a mst unplug after hpd off. But sometimes
disconnect thread freezes waiting for audio ack. During this freeze
unplug happens and uninstalls connector and free the panel and audio
objects due to which lock associated with completion variable causes an
exception.

Currently,power resource disable fails when pm_runtime_put_sync
returns negative values. Due to this, clock state update is
failing. pm_runtime_put_sync can return negative values in
scenarios where pending resume requests take precedence over
suspends. This change allows pm_runtime_put_sync to return
negative vales also.

Currently, power_state variable does not reflect the GDSC
status. Due to this, there are scenarios where ctrl_power_on
is not happening leading to clock failures. This change
updates power_state based on current status of all the
regulators. GDSC enable is moved to pre_clkon and GDSC
disable is moved to post_clkoff.

Plane update will call system cache update, and by default,
will clear any cache programming. This clear is only necessary
after returning from a cached state. This change will reduce
unnecessary programming and event logs if the sys cache
was previously disabled and remains disabled.

Return early if the active streams are not present. Clean function
doesn't take into account the count of active stream which is being
changed during disable and link clk is turned off before that.
Adding active stream check in pre_off will ensures atleast one
stream is on and link clk is not turned off.
