Hello Pranay,

This test iterates on all the available edids of HDMI.
Due to CI test timeut limitation, we are reducing the
number of edids to execute to avoid result as timeout.

Using extended flag to achieve this. The test will execute
only 25 edids when this flag is not used as CI doesnt uses
this flag.
In local execution to execute on all edids, we have to give
this flag at the runtime.

Is there any environment variable that can be checked here instead of using extended?
If we can somehow know that this is a CI execution with some environment variable we can use that instead.
It will allow executing test without extended flag.

If we don't have any such env variable I am ok with this approach just add a info message to notify
user we are shortening the list also add a intel platform check.
