[igt-dev] [PATCH i-g-t v6 1/2] tests/kms_async_flips: Convert tests to dynamic

[Karthik B S]

v2: -Get the mode after igt_display_reset() (Bhanu)

v3: -Move patch to start of series to avoid code duplication (Bhanu)
    -Use for_each_pipe() instead of for_each_pipe_static() (Bhanu)

v4: -Add helper to avoid code duplication (Andre)
