Subject: [PATCH] bus: mhi: host: Add firehose support for Foxconn SDX24/SDX55/SDX65

Since we implement the FIREHOSE channel support in foxconn mhi
channels, that means each product which use this channel config
would support FIREHOSE. But according to the trigger_edl feature,
we need to enable it by adding '.edl_trigger = true' in device
info struct.
Also, we update all edl image path from 'qcom' to 'fox' in case of
conflicting with other vendors.
