The Atom/SST driver does not rely on ASoC power management, but the
SOF driver does. Rather than using a hard-coded build-time assignment,
we can set this pm_ops dynamically depending on what the parent
is. That will remove the last build-time dependency and allow for
coexistence of both SST and SOF drivers for Baytrail/Cherrytrail.

To avoid hard-coded variations between SOF and SST drivers, set the
card name and driver dynamically depending on the parent type. This is
the first pass required to let distributions select which drivers to
use with kernel parameters instead of build-time selection.

Blindly adding an sof- prefix to the card name is not user friendly
and causes UCM issues with a driver name truncated to 16 characters.
Simplify to use "sof-bytcht <codec_name>" pattern for all byt* machine
drivers. The sof- prefix is added by the core. A generic "SOF" driver
name is used, and UCMv2 will detect the configuration for this driver
by testing the card name.
Legacy uses are unmodified.

Add required .pm_ops to support suspend/resume on baytrail/cherrytrail
machines.
This .pm_ops is conditionally-added to avoid impacting the legacy
driver where power management is handled differently.

The API, which belongs to GPIO library, is foreign to ACPI headers. Earlier
we moved out I²C out of the latter, and now it's time for
acpi_dev_add_driver_gpios() et al.
For time being the acpi_gpio_get_irq_resource() and acpi_dev_gpio_irq_get()
are left untouched as they need more thought about.
Note, it requires uninline acpi_dev_remove_driver_gpios() to keep purity of
consumer.h.

This is an implementation of a machine driver needed for Conexant
CX2072X codec on Intel Baytrail and Cherrytrail platforms. The
current patch is based on the initial work by Pierre-Louis Bossart and
the other Intel machine drivers.
The jack detection support (driven via the standard GPIO) was added on
top of the original work.
Tested with ASUS E200HA laptop.
