Subject: [PATCH] remoteproc: stm32: demote warning about optional property absence

The mainline device trees lack the "st,syscfg-pdds", so probing the
driver always throws the warning. As the property is optional per binding
and the driver can deal with its absence, demote the warning to info log
level.
