From: Vinod Koul <vinod.koul@intel.com>
The PCM interface in SST driver is cmds only, this patch changes the interface to open, close and cmd interface.
This allows SST driver to keep easy track of handles open

The firmware name for each platform is appended by PCI id of device.
This patch makes use of pci id to construct the string rather than
hardcode the string.

scu ipc driver fails sometimes to read/write. This add logs with register
addr and ret code when these errors occur.

This patch adds two new ioctls to intel_sst_ctrl device.
This i/f can be used by application to send algorithm parameters
Signed-off-by: Vinod Koul <vinod.koul@intel.com>
[This will need further discussion in the context of the final ALSA interface
but is fine for staging, ie anyone who relies on it should expect changes
Also fixed a missing kmalloc fail check]

I edited this one by hand to get it to apply, but the other 7 were
harder. Can you redo them and resend them as the pr_debug() changes
that are now in staging-next are massivly conflicting with this series.
