This patch fixes compile errors for kernel 4.9. Kernel 4.9 has two
changes, struct snd_soc_codec_driver is modified and changed PCM
runtime array to a list from struct snd_soc_card.

There are a couple issues with system suspend handling in the Tegra
ASoC codec drivers which are:
1. Most drivers the system suspend callback does nothing and this
means that if the codec device is active when suspend occurs then
the codec will not be suspended correctly. This has been seen to
cause system crashes in the I2S driver when the system is suspended
and resuming while audio playback is active.
2. The codec suspend handlers may be called twice when entering
suspend. Suspend handlers should only be called once, but currently
they are called twice; once by the PM core and once when the APE
power-domain is turned off (if it is on when suspend occurs).
Fix the above two problems by:
a). Adding proper system suspend and resume handlers for all codec
drivers, to suspend and resume the device if not runtime PM
suspended on entering suspend.
b). Remove the code to call the PM callbacks from the APE power-domain
code.
Finally, make the system suspend callbacks for these codec drivers
late suspend callbacks to ensure that the sound core has suspended
any on-going activity, before we attempt to suspend these codec
devices.

Linux runtime PM automatically handles the runtime resuming and
suspending of a parent device and therefore, it is not necessary
for a child device to explicitly runtime resume or suspend the
parent.
The various Tegra ASoC codec drivers explicitly runtime resume
and suspend the parent device from within their runtime PM callback
handler. This should not be necessary.
Furthermore, currently the various Tegra ASoC codec drivers are
not suspended correctly if active when system suspend occurs. During
system suspend it is common to directly call the runtime PM callbacks
to suspend and resume the device if active from the system suspend
callbacks. However, the APIs, pm_runtime_get/put(), cannot be called
during system suspend and so the runtime PM callbacks for these codec
drivers cannot be called from the context of the system suspend
callbacks.
Remove the calls to runtime resume and suspend the parent device from
the runtime PM callbacks for the various Tegra ASoC drivers. This will
allow us to fix suspending and resuming of the Tegra ASoC drivers
across system suspend.

Below are the hypothetical scenarios
- Drivers are in suspend state while reboot and PCM Open call from
userspace is received after driver shutdown [APE is power gated
already]
- PM domain handling doesn't ensure proper functionality after driver
shutdown is called
The change handles with the below fix
- ALSA PCM Open API first executes runtime resume of each driver.
So need to prevent any reg access in runtime resume of drivers.
- ALSA PCM Open executes ADMAIF startup after runtime resume of
each driver. If ADMAIF startup returns failure based on shutdown,
PCM Open operation will fail, this will break PCM Open path and
will ensure no further ALSA APIs/Callbacks are called.
