ucm2: Qualcomm: add Dell XPS 9345
Add a Regex string, seems to be mostly compatible with Yoga Slim7x. x4 speakers, x2 DMICs (unlike Yoga's 4), x2 DP, no headphone jack. DMI_info evaluates to Dell Inc.-XPS-0DXPNM. It appears to be okay to re-use Yoga, as only 2 microphone channels are considered.
Audio part of Dell XPS 9345 DT is available out of tree, will be submitted to the lists shortly. audioreach-topology was merged a while ago.
Tested that speakers, MICs are working.
Known issues: L and R sides are swapped due to kernel driver not taking DT labels into account just yet, and particular platform having WSAs connected to different soundwires interfaces than the rest of x1e80100 devices. Identified by Abel Vesa at Linaro. Fix will be on the kernel and/or DT side.
For unknown reason, board_name on this machine is 0DXPNM, which is a bit cryptic and I am not sure it will be the same on all XPSs. Ill extend DMI_info with product_name and add that one instead.
