Subject: [PATCH 07/16] device connection: use new match_string() helper/macro

The `device_connection` struct is defined as:
struct device_connection {
        struct fwnode_handle    *fwnode;
        const char              *endpoint[2];
        const char              *id;
        struct list_head        list;
};

The `endpoint` member is a static array of strings (on the struct), so
using the match_string() (which does an ARRAY_SIZE((con->endpoint)) should
be fine.

The recent change to match_string() (to ignore NULL entries up to the size
of the array) shouldn't affect this.
