dt-bindings: phy: Add PHY_TYPE_XAUI definition

XAUI (eXtended Attachment Unit Interface) is a high-speed serial interface
standard for 10 Gigabit Ethernet (10GbE). It uses four lanes with each
lane operating at 3.125 Gbps (totaling 10 Gbps), to extend the XGMII
interface across circuit boards, commonly used in backplanes for
networking switches and high-performance computing. XAUI is defined as a
standardized instantiation of XGMII Extender in the IEEE 802.3
specification.

Add definition for XAUI PHY type.
