drm/xe: Enable PCI device earlier

Newer Intel platforms require that inspect the contents of the GMD_ID
registers very early in the driver initialization process to determine
the IP version (and proper init sequences), of the platform.  Move the
general PCI device setup and enablement slightly earlier, before we
start trying to peek at the GMD_ID registers.
