[Intel-gfx] [PATCH 2/3] drm/i915/tgl: allow the reg_read ioctl to read the RCS TIMESTAMP register

[Lucas De Marchi]

From: Jordan Justen <jordan.l.justen at intel.com>

This enables the Mesa driver to advertise support for ARB_timer_query,
and thus an OpenGL version higher than 3.2.

Based on the ICL patch by Paulo Zanoni and CNL patch by Nanley Chery.
