Subject: [RFC PATCH net-next 02/22] net: dsa: mt7530: use p5_interface_select as data type for p5_intf_sel

From: Arınç ÜNAL <arinc.unal@...nc9.com>

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.
