Agreed, I don't have access to hardware with _PR3 support to install the
Qualcomm devices - all my testing for these has been on platforms without
_PR3 (desktop M.2 adapters).
I'll drop the general d3cold infrastructure (patch 1/3) entirely and simplify
patch 2/3 to just a D3hot-only device-specific reset for the specific Qualcomm
devices where testing shows it works despite NoSoftRst+.

v9 coming soon.

Thanks,

Best regards
Jose Ignacio
