Add PCI IDs for Intel CometLake platforms, which from a software

Humm, I have mixed feelings here.
Yes the hardware is nearly identical, with the exception of one detail
that's not visible to the kernel, but there is no support for DMICs with
the Skylake driver w/ HDaudio, and Chrome platforms are only going with
SOF, so is it wise to add these two CometLake platforms to the default
SND_SOC_INTEL_SKYLAKE selector, which is used by a number of distributions?
I don't mind if we add those PCI IDs and people use this driver if they
wish to, but it may be time for an explicit opt-in? The
SND_SOC_INTEL_SKYLAKE definition should even be pruned to mean SKL, APL,
KBL and GLK, and we can add DMI-based quirks for e.g. the Up2 board and
GLK Chromebooks which work with SOF.
