Subject: [PATCH V6 4/5] remoteproc: qcom: Add support for q6v5-wcss pil
IPQ8074 has an integrated Hexagon dsp core q6v5 and a wireless lan
(Lithium) IP. An mdt type single image format is used for the
firmware. So the mdt_load function can be directly used to load
the firmware. Also add the relevant resets required for this core.
