[PATCH net] net: pcs: xpcs: fix incorrect number of interfaces

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

In synopsys_xpcs_compat[], the DW_XPCS_2500BASEX entry was setting
the number of interfaces using the xpcs_2500basex_features array
rather than xpcs_2500basex_interfaces. This causes us to overflow
the array of interfaces. Fix this.
