We need to be able to specify GPIO flags in devicetree without that
preventing translation from the Arduino specifier to the host GPIO
specifier. Set up to ignore the low 6 bits of the flags field when
matching the child specifier, and to copy those bits to the parent
specifier.

Create a dedicated connector file to hold arduino connector
information for disco_l475_iot board.
This should enhance board dts file readability.
