Hi Alex,

Ok, I'll make the comment of the function more specific for these Qualcomm
devices.

No, I don't have access to platforms with _PR3 support. All testing was on
M.2 adapters (D3hot fallback only). Since D3hot works reliably and D3cold
is a stronger reset mechanism, the approach should work - but I cannot
confirm the D3cold path through testing.

I'll send v9 with the updated comment.

Thanks,
Jose Ignacio
