[igt-dev] [PATCH i-g-t v3 4/5] tests/i915_pm_lpsp: screens-disabled subtest use igt_wait

[Anshuman Gupta]

When all screens are disabled, it takes some time to release
eDP/DP AUX IO power domain ref count. Also, delayed audio codec
disabling takes time to release AUDIO power domain ref-count,
using igt_wait to check lpsp after disabling all screens.
