[RFC PATCH net-next v2 03/11] net: phy: introduce phy_interface_copy helper

Introduce phy_interface_copy helper as a shorthand to copy the PHY
interface bitmap to a different location.

This is useful if a PHY interface bitmap needs to be stored in a
different variable and needs to be reset to an original value saved in a
different bitmap.
