Add support for cs42l45 into the Intel machine driver

Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:

Now that the full class driver is in place we can add support to the
Intel machine driver for Cirrus's new SDCA audio CODEC the cs42l45. This
makes some minor tweaks to the machine driver itself to support SDCA
devices, and then adds the necessary tables etc. to define the device.

Note, this series shouldn't have any dependencies on the other series of
improvements to the class driver that is already on the list. So either
can be merged first.
