(See annex 28B.2 and 28D). The old mii.h defined ANAR_X_PAUSE_* macros. Those
macros were named for 1000Base-X, but the bit definitions were not for
1000Base-X but for others (e.g. 1000BaseT). So there was bug in auto
negotiation for 1000Base-X, but there was no bug for other media. Define new
macro named ANAR_PAUSE_* and ANLPAR_PAUSE_* for other than 1000Base-X and fix
the bit definitions of ANAR_X_PAUSE_* and ANLPPAR_X_*. Change some PHY drivers
to use true macro. Same as other *BSDs.
