regulator: Fixes for v6.14

Browse Source 
The main change here is a revert for a cleanup that was done in the
 core, attempting to resolve some confusion about how we handle systems
 where we've somehow managed to end up with both platform data and device
 tree data for the same device.  Unfortunately it turns out there are
 actually a few systems that deliberately do this and were broken by the
 change so we've just reverted it.
 
 There's also a new Qualcomm device ID.
