Ashutosh Dixit b6fd51c621 drm/xe/oa/uapi: Define and parse OA stream properties
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)
