[igt-dev] [PATCH i-g-t v2 1/3] tests/psr: Prepare for moving PSR state checking functions into lib

[Dhinakaran Pandiyan]

Change the function arguments to not rely on test specific data as
the following patches change kms_frontbuffer_tracking to reuse PSR
functions.

v2: Leave --no-psr intact (Rodrigo)

[igt-dev] [PATCH i-g-t v2 2/3] tests/psr: Move PSR state test functions to lib

[Dhinakaran Pandiyan]

kms_frontbuffer_tracking and kms_psr test PSR in different ways, let'
fix that by creating common library functions.

v2: Include the new file in meson.build
v3: Leave --no-psr intact (Rodrigo)

I wonder if we shouldn't change it to only get the fd
and here for instance use igt_assert(!psr_active...

anyways this can be in separated patch
