dt-bindings: net: qcom,ipa: add firmware-name property
Add a new optional firmware-name property to the IPA DT node. It
is used only if the modem is not doing early initialization (i.e.,
if the modem-init property is not present). Its value is the name
of the firmware file to use; if it's not specified, a default name
("ipa_fws.mdt") is used.
