When the driver core calls the probe callback it already checked that
the devices match, so there is no need to call the match callback again.

Hi Uwe,

Just remembered the similarity in SCMI when you posted similar patches
for Arm FF-A. Thought I will push this out before I forget. I have put
suggested and reported by you as I don't have upstream commit id to refer
yet. Hope that is fine.

Regards,
Sudeep
