ASoC: SOF: Intel: add initial SKL/KBL hardware support
In preparation of the IPCv4 IPC support, this patch adds support for SkyLake and KabyLake boot and descriptors used when probing the PCI driver. The work was initially contributed in 2018 by Liam Girdwood and Zhu Yingjiang, and abandoned due to firmware signature issues. With the upcoming support of IPC v4, and hence the Intel closed-source firmware, it's time to re-add this capability. The SKL ops will be added in the next patch. Tested with the IPC4 and closed-source firmware on Dell XPS 9350 and KBL NUC with HDaudio codecs. The SSP and DMIC interfaces are not supported at this time.
