drm/amdgpu: Fix consecutive DPC recovery failures.
Cache the PCI state on boot and before each case where we might
loose it.
v2: Add pci_restore_state while caching the PCI state to avoid
breaking PCI core logic for stuff like suspend/resume.
v3: Extract pci_restore_state from amdgpu_device_cache_pci_state
to avoid superflous restores during GPU resets and suspend/resumes.
v4: Style fixes.
