From: Slark Xiao <slark_xiao@xxxxxxx>
commit a7bc66fe8093b48e86386cf73dd601feaaa7949c upstream.
Foxconn uses a unique firmware for their MHI based modems. So the generic
firmware from Qcom won't work. Hence, update the EDL firmware path to
include the 'foxconn' subdirectory based on the modem SoC so that the
Foxconn specific firmware could be used.
Respective firmware will be upstreamed to linux-firmware repo.
