net: dsa: mt7530: use p5_interface_select as data type for p5_intf_sel

Use the p5_interface_select enumeration as the data type for the
p5_intf_sel field. This ensures p5_intf_sel can only take the values
defined in the p5_interface_select enumeration.

Remove the explicit assignment of 0 to P5_DISABLED as the first enum item
is automatically assigned 0.
