Why do we need this change? will igt_display_reset() clear this data?

Reset is not required here, also we need to use 
igt_display_require_output() instead of having valid_tests variable.

Also, can we have a new patch to convert kms_concurrent to dynamic subtests?

Also, can we have a new patch to convert kms_sequence to dynamic subtests?
