The 0001-xxx.patch is for adding the ICL pciid, it is not in the bionic kernel,
so bionic kernel needs two patches.

The 0002-xxx.patch is in the upstream from v5.2-rc1, it is needed for b/c/d/e.

We have some cometlake machines, after installing the bionic kernel, the sound
can't work at all, we found the sound driver didn't load into the kernel.

After add the pciid in the pci_driver, the sound driver can be loaded and sound
worked well.

[Test Case]
Boot the system and play sound or record sound, they all worked well

[Regression Risk]
Low. Adding new pciid, will not change existing functions.
