[PATCH i-g-t 1/2] RFC: chamelium/kms_chamelium_hpd: add helper function to select connector port

[Moahmmed Bilal <mohammed.bilal@intel.com>]

From: Mohammed Bilal <mohammed.bilal@intel.com>

Introduce a new helper function get_port() which returns the
chamelium_port matching the requested connector type.
The helper iterates through the available ports and
returns the first match, or NULL if no matching connector is found.
