[igt-dev] [PATCH] lib/igt_chamelium: Extend check of valid ports to port=0

[Mark Yacoub]

[Why]
Chamelium V3 has a valid port at 0 so 0 should not be rejected.

[How]
Check for port values between 0 and CHAMELIUM_MAX_PORTS which should
also include the V2 ports range.

Test: ./kms_chamelium --run-subtest dp-hp
Tested on: Volteer & cv3
