lib/psr: Add support to new modified i915_edp_psr_status output

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.

In psr_active() we were overdoing, we just need to check the source
state to know if PSR is active and doing that we keep compability to
old and new i915_edp_psr_status output.
