drm/i915/pci: move intel_pci_config.h under include/drm/intel

Since the PCI registers are used from both i915 display and core, move
intel_pci_config.h to include/drm/intel/pci_config.h. Drop the intel_
prefix from the name to reduce tautology.

With this, we can drop the corresponding xe display compat header.

v2: Rebase
