Like done with other functions, cleanup the error handling in
xe_device_probe() by moving the OA fini to be handled by xe_oa
itself, which relies on devm to call the cleanup function.

Properties for OA streams are specified by user space, when the stream is
opened, as a chain of drm_xe_ext_set_property struct's. Parse and validate
these stream properties.
v2: Remove struct drm_xe_oa_open_param (Harish Chegondi)
Drop DRM_XE_OA_PROPERTY_POLL_OA_PERIOD_US (Umesh)
Eliminate comparison with xe_oa_max_sample_rate (Umesh)
Drop 'struct drm_xe_oa_record_header' (Umesh)
v3: s/DRM_XE_OA_PROPERTY_OA_EXPONENT/ \
DRM_XE_OA_PROPERTY_OA_PERIOD_EXPONENT/ (Jose)
v4: Fix 32 bit build
v5: Add non-static function kernel doc (Michal)

Introduce add/remove config perf ops for OA. OA configurations consist of a
set of event/counter select register address/value pairs. The add_config
perf op validates and stores such configurations and also exposes them in
the metrics sysfs. These configurations will be programmed to OA unit HW
when an OA stream using a configuration is opened. The OA stream can also
switch to other stored configurations.
v2: Start config id's from 1 and other minor review comments (Umesh)
v3: Add 32 bit build
v4: Add kernel doc for non-static functions (Michal)
