[PATCH v1 10/10] tests/intel/xe: Remove xe_uevent for now

[Francois Dugast]

From: Rodrigo Vivi <rodrigo.vivi at intel.com>

This kernel uevent is getting removed for now. It will come
back later with a better future proof name.

v2: Align with kernel commit ("drm/xe/uapi: Remove reset uevent \
    for now") (Francois Dugast)
