Add suspend and resume support to Baytrail SST DSP. This is implemented by
unloading firmware modules and putting DSP into reset prior suspend and
restarting DSP again in normal boot state after resume.

Context restore for running streams is implemented by scheduling a work from
sst_byt_pcm_trigger() that will allocate a stream with existing parameters
and start it from last known buffer position before suspend.

Suspend/resume requires reloading FW to boot state so we need to also make

We have to save the physical address of extended firmware block in the
beginning of mailbox every time when we boot the DSP firmware since that
mailbox address is re-used after DSP firmware is running. Otherwise DSP
firmware will get bogus extended firmware block address during next DSP
boot.

Currently this is not problem but becomes when DSP runtime rebooting is
implemented. Prepare for that by moving extended firmware address saving
from sst_byt_init() to sst_byt_boot().

Baytrail ADSP stream IPC simplifies a little by moving IPC_IA_START_STREAM
construction and sending directly into sst_byt_stream_start() from
sst_byt_stream_operations(). This is because IPC_IA_START_STREAM is only
stream IPC with extra message data so this move saves a few code lines.

Main motivation for this is to prepare for passing stream start position
to sst_byt_stream_start() which will be needed in resume code.

This is for preparing suspend/resume support but can give also more
safeguard against concurrent timestamp structure access between DSP firmware
and host.

Now DSP DMA pointer is sampled in each pcm pointer callback in
sst_byt_pcm_pointer() but that is unneeded since DSP updates the timestamp
period basis and can potentially be racy if sst_byt_pcm_pointer() is called
when DSP is updating the timestamp.

By taking DSP DMA pointer only after period elapsed IPC messages in
byt_notify_pointer() and returning stored hw pointer in
sst_byt_pcm_pointer() there is less risk for concurrent access.

The same stored hw pointer can be also used in suspend/resume code for
restarting the stream at the same position.

The BCP bit in TCR4/RCR4 register rules as followings:
  0 Bit clock is active high with drive outputs on rising edge
    and sample inputs on falling edge.
  1 Bit clock is active low with drive outputs on falling edge
    and sample inputs on rising edge.

For all formats currently supported in the fsl_sai driver, they're exactly
sending data on the falling edge and sampling on the rising edge.

However, the driver clears this BCP bit for all of them which results click
noise when working with SGTL5000 and big noise with WM8962.

Thus this patch corrects the BCP settings for all the formats here to fix
the nosie issue.

Before we had card level support for DAPM and controls machine drivers would
register their controls and DAPM elements with the CODEC. This required us to
temporarily unset the name_prefix of a CODEC during the rtd init callback to
avoid the machine level controls getting the CODEC's prefix. Now that all
machine drivers properly register their machine level controls and DAPM elements
with the card rather than with the CODEC we can drop the hack that sets the
CODEC's name_prefix to NULL while calling the DAI link or AUX dev init callback.
