zephyr: i2c mapping using an enum
Currently, every project will need to provide a custom mapping header
for i2c as well as gpios. We'd like to move that overhead to the dts
files, which will make the board dts a lot more reusable as well as
clean up the bringup of new boards.
Add to the i2c_ports enum from the dts named i2c port list. Each enum
is only added if a node exists using that enum. This also allowes for
verifying that the enum is only used once.
