This really sneaked through. I shouldn't have allowed this path. We should bite
the bullet and use a standard path for all modems as Dmitry suggested. So the
path will become:
"qcom/<chip>/<vendor>/" where chip is 'sdx72m' and vendor is 'foxconn'.
If you need to use product specific firmware, then
"qcom/<chip>/<vendor>/<product>"
Since the firmware itself is not upstreamed to linux-firmware, changing the path
is not a big deal.
