drm/xe/d3cold: Set power state to D3Cold during s2idle/s3
According to pci core guidelines, pci_save_config is recommended when the
driver explicitly needs to set the pci power state. As of now xe kmd is
only doing pci_save_config while entering to s2idle/s3 state, which makes
pci core think that device driver has already applied required pci power
state. This leads to GPU remain in D0 state. To fix the issue setting
the pci power state to D3Cold.
