[igt-dev] [PATCH i-g-t 2/2] tests/i915_pm_dc: Wait for PSR2 entry

["José Roberto de Souza" <jose.souza@intel.com>]

After enable PSR2 we can not check right away if PSR2 is enabled, we
need let some time to PSR2 to be enabled.
For that we have psr_wait_entry(), that is why the previous patch was
reverted as psr_enabled() is not much useful.
