[igt-dev] [PATCH i-g-t 2/2] lib/psr: Add support to new modified i915_edp_psr_status output

[José Roberto de Souza]

The kernel patch 'drm/i915: Refactor PSR status debugfs' changed the
output of i915_edp_psr_status, so adding support to the new output
here while keeping the support to the old one for a while.
