We currently read debugfs every 1 ms, given that it takes about 140 ms
for PSR entry on the CI machines and entry can occur at frame time
intervals, bump the debugfs read interval to 20 ms.

PSR appears to not exit immediately after the test commits a page flip,
give some leeway for PSR to idle. Let's set the timeout at 40 ms with a
5 ms interval between each status read.

Let's rename to debugfs_fd all the parameters of the functions that
expect debugfs fd to avoid call one those functions with the wrong
file descriptor.

The tests calls igt_debugfs_dir() to open the debugfs dir and further
along calls igt_debugfs_read() each time i915_edp_psr_status needs to be
read. As igt_debugfs_read() opens the directory unnecessarily, switch to
using the newly added igt_debugfs_simple_read()

It's harmful to write to enable_psr at runtime, and the patch that allows
us to change i915_edp_psr_debug with the panel running will require us
to abandon the module parameter. Hence the userspace change needs to be
put in IGT first before we can change it at kernel time.
Toggling it to debugfs will mean we can skip a modeset when changing our
feature set.
Changes since v1:
- Rebase with the previous patches dropped.
Changes since v2:
- Rebase on top of new api in i915_edp_psr_debug.
Changes since v3:
- Enable IRQ debugging for extra logging.
- Force PSR1 mode. (dhnkrn)
- Move PSR enable/disable functions to lib/igt_psr. (dhnkrn)
Changes since v4:
- Redisable irqs right away when debugfs api doesn't work. (dhnkrn)
- Use hex everywhere. (dhnkrn)

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)
