zephyr: volteer: init i2c_ports
Populate i2c_ports[] and set i2c_ports_used correctly.
Add child bindings for named i2c ports that allow configurations. A
configured named i2c node MUST have a kbps property and 2 child nodes
for `scl` and `sda` which will use the same enums as the named gpios.
This provides a compile-time check to make sure that the overlay
gpio.dts defined a named gpio using the SCL/SDA enums. This means
that if the i2c port config uses a valid enum from gpio-enum-name.yaml
but the overlay did not define a node using that same enum, the build
will break (because the gpio_signal enum will not have that enum
defined).
