intel_de_{read,write}8() aren't performance critical so having them
as static inline is pointless. Introduce intel_de.c and move the
implementation there.

Add .framebuffer_init, .framebuffer_fini and .framebuffer_lookup to the bo parent interface. While they're about framebuffers, they're specifically about framebuffer objects, so the bo interface is a good enough fit, and there's no need to add another interface struct.

Continue i915 and xe separation from display by moving the bo calls to the display parent interface. Instead of adding all these functions to intel_parent.[ch], reuse the now vacated intel_bo.[ch], and avoid mass renames to calls of these functions. This is similar to intel_display_rpm.[ch]. Make many of the hooks optional to avoid having to implement dummy functions in xe. Indeed now we can remove many of the existing dummy functions.

Move the get/put/ref/flush_for_display calls to the display parent interface. For i915, move the hooks next to the other i915 core frontbuffer code in i915_gem_object_frontbuffer.c. For xe, add new file xe_frontbuffer.c for the same. Note: The intel_frontbuffer_flush() calls from i915_gem_object_frontbuffer.c will partially route back to i915 core via the parent interface. This is less than stellar.

Allocate correctable, uncorrectable nodes for every xe device. Each node
contains error component, counters and respective query counter functions.
Add basic functionality to create and register drm nodes.
Below operations can be performed using Generic netlink DRM RAS interface:
1) List Nodes:
$ sudo ynl --family drm_ras --dump list-nodes
[{'device-name': '0000:03:00.0',
'node-id': 0,
'node-name': 'correctable-errors',
'node-type': 'error-counter'},
{'device-name': '0000:03:00.0',
'node-id': 1,
'node-name': 'uncorrectable-errors',
'node-type': 'error-counter'}]
2) Get Error counters:
$ sudo ynl --family drm_ras --dump get-error-counter --json '{"node-id":0}'
[{'error-id': 1, 'error-name': 'core-compute', 'error-value': 0},
{'error-id': 2, 'error-name': 'soc-internal', 'error-value': 0}]
3) Get specific Error counter:
$ sudo ynl --family drm_ras --do get-error-counter --json '{"node-id":0, "error-id":1}'
{'error-id': 1, 'error-name': 'core-compute', 'error-value': 0}
