[CI 2/2] drm/xe/pm: Re-enable D3Cold by default on BMG

[Rodrigo Vivi]

This patch re-enables D3Cold by default on BMG.

If issues on runtime_pm resume are seen and the D3cold->D0 transition
is suspected to block the device or cause memory corruptions, D3cold
can be disabled for confirmation with either:

1. at runtime:
   echo 0 > /sys/bus/pci/devices/<addr>/vram_d3cold_threshold

2. at boot:
   pcie_port_pm=off

Upon confirmation of D3Cold related bug, please file a bug to the
link below.
