While going to shutdown, we need to bring HW to clean state. This
is done by cleaning up stream descriptor registers. This cleanup
is already done by decoupling of stream and stopping the chip, so
invoke these from shutdown handler.

The driver used autosuspend delay to delay going to D3. But per
HW recommendation we should go to D3 soon, so remove the delay
from driver

In active suspend, any HDA interrupt should wake the system. When device
enters active suspend, we need to enable HDA controller interrupt as wake
source. Similarly disable HDA controller interrupt as wake source when
exiting active suspend.

When device enters active suspend, we should turn off the links
as they are not in use. Similarly we need to bring back links
when we exit active suspend.

MISCBDCGE is a new register for Misc Backbone clock gate control
which is useful to control while resetting the link and ensuring
controller is in required state so add API to control it
HW recommends that we reset with CGCTL.MISCBDCGE disabled, so add
that while doing init chip and reset sequence.

Some of the usecases can be marked as 'ignore_suspend' by
machine. For these on suspend we should keep audio controller
ON by saving the state and not suspending the device
For this we need to maintain a counter for these streams and be
active on suspend when such a stream is opened.

For HDA codecs WAKEENABLE bit is to programmed if codec event
change has to wake the system when suspended.
In skylake I2S systems which are currently supported we have
only HDMI codec, which doesn't use this capability to detect a
HDMI connect/ disconnect event. HDMI HDA codec uses display
interface to detect connect/disconnect event.
This patch removes the WAKEBIT enabling during device D0/D3 as
this seems to cause spurious wakes on the system

The driver runtime behaviour is fine but in suspend, we missed
setting the DSP to suspend and also missed resuming DSP on
resume.
Fix this by having common SKL suspend and resume routines which
power up/down links, suspend/resume DSP and other common
routines, and call these routines from both runtime as well as
system PM handlers
