[igt-dev] [PATCH i-g-t v2 5/9] lib/igt_chamelium: add CHAMELIUM_MAX_PORTS

[Simon Ser]

We will always be able to find an upper bound for the number of connectors
supported by a Chamelium board. Instead of using dynamic arrays, simplify the
code by using static ones.

More code will need to have arrays of ports in the future.
