Subject: [PATCH net-next 05/16] net: pcs: xpcs: Move native device ID macro to linux/pcs/pcs-xpcs.h

Generic MDIO-device driver will support setting a custom device ID for the
particular MDIO-device. Generic DW XPCS ID can be used for that as well
just in case if the DW XPCS-device was erroneously synthesized with no or
some undefined ID. In addition to that having all supported DW XPCS device
IDs defined in a sinle place will improve the code maintainability and
readability.

Note while at it rename the macros to be shorter and looking alike to the
already defined NXP XPCS ID macro.
