Hook CRI get-error-counter and clear-error-counter support to
xe_drm_ras to allow userspace to query and clear counters if supported.
Integrate this with xe_drm_ras.
Usage:
Query all error counter value using ynl
$ 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},
{'error-id': 3, 'error-name': 'device-memory', 'error-value': 0},
{'error-id': 4, 'error-name': 'pcie', 'error-value': 0},
{'error-id': 5, 'error-name': 'fabric', 'error-value': 0}]
Query single error counter value using ynl
$ sudo ynl --family drm_ras --do get-error-counter --json \
'{"node-id":1, "error-id":1}'
{'error-id': 1, 'error-name': 'core-compute', 'error-value': 2}
Clear counter using ynl
$ sudo ynl --family drm_ras --do clear-error-counter --json '\
{"node-id":1, "error-id":1}'
None

cleanup_node_param() is not registered for previous node in case of counter
allocation failure, which results in stale memory of previous node that
isn't cleaned up on unwind. Add per node cleanup action which guarantees
cleanup on unwind and also simplifies the cleanup logic.

cleanup_node_param() is not registered for previous node in case of counter
allocation failure, which results in stale memory of previous node that
isn't cleaned up on unwind. Fix this using drm managed allocation, which is
guaranteed to be cleaned up on unwind.

Add support for clear-error-counter command in XE drm_ras
This resets the counter value.
Usage:
$ sudo ynl --family drm_ras --do clear-error-counter --json \
'{"node-id":1, "error-id":1}'
None

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}
