Log Message:
switch to using OpenBSD eehpy(4) code to drive maphy(4), synchronizing support
for several special PHY conditions, particularly:
- Properly re-initialise the PHY upon resume
- Store next page in the Link Partner Next Page register for compatibility
  with 802.3ab on 88E3016 PHYs.  Fixes some autonegotiation problems on msk(4)
- Make 88E3016 actually work
- Make sure page 0 is selected when we initialize the PHY.  Fixes problems
  with the eephy(4) that attaches to nfe(4) on machines like the Sun Ultra 40.
  (we had condition for this, now the page 0 is selected for any PHY type)
- Disable fiber/copper auto-selection on the 88E1111 if it is in RGMII mode, to
  work around the fact that the onboard PHYs attached to nfe(4) on the Sun
  X4100 M2 have fiber/copper auto-selection enabled even though the interfaces
  are clearly copper-only

make sure to also add appropriate licenses, since basically nothing
really significant remains out of previous code

use FreeBSD <dev/mii/e1000reg.h> for register definitions as a base instead
of OpenBSD <dev/mii/eephyreg.h>, since it has some extra definitions for some
3016 bits, but add the several extra bits from OpenBSD needed by the code;
removed no longed used <dev/mii/makphyreg.h>

tested with PHY 88E1111, there no particular change observed - the
link status works as it did before, just now it does media nego
even before the interface is up

should however fix 88E3016 support and hence PR kern/49270 and PR kern/53301
