ASoC: atmel: atmel_ssc_dai: move .suspend/.resume to component

There is no big difference at implementation for .suspend/.resume
between DAI driver and Component driver.
But because some driver is using DAI version, thus ALSA SoC needs
to keep supporting it, hence, framework becoming verbose.
If we can switch all DAI driver .suspend/.resume to Component driver,
we can remove verbose code from ALSA SoC.

Driver is getting its private data via dai->dev.
But dai->dev and component->dev are same dev, thus, we can convert
these. For same reason, we can convert dai->active to
component->active if necessary.

This patch moves DAI driver .suspend/.resume to Component driver

ASoC: atmel_ssc_dai: Remove wrong spinlock usage

A potential bug was reported in the email "[BUG] atmel_ssc_dai: a
possible sleep-in-atomic bug in atmel_ssc_shutdown"[1]

Indeed in the function atmel_ssc_shutdown() free_irq() was called in a
critical section protected by spinlock.

However this spinlock is only used in atmel_ssc_shutdown() and
atmel_ssc_startup() functions. After further analysis, it occurred that
the call to these function are already protected by mutex used on the
calling functions.

Then we can remove the spinlock which will fix this bug as a side
effect. Thanks to this patch the following message disappears:

"BUG: sleeping function called from invalid context at
kernel/locking/mutex.c:909"
