Add support for the Motorcomm YT8521/YT8531 PHYs. Since these PHYs may
need various board-dependent tweaks, pass the device tree node down
to the PHY driver such that we can look at various properties to make
the necessary tweaks. Enable ytphy(4) on riscv64.

Implement software control for the internal delays of the RTL8211F PHY.
Since we need to retain the hardware/firmware configuration of the delays
in most existing hardware that uses rgephy(4) (such as PCIe NICs), add a
bew MIIF_SETDELAY flag that controls the software configuration of the
delays.

The Marvell 88E1512 supports multiple modes between MAC to PHY and PHY
to Media. The mode can be configured in the General Control Register 1.
On the 88E1512 and 88E1514 this mode defaults to 111 (invalid). Thus we
need to change the mode if we want SGMII-to-Copper. For this, allow the
interface to pass an SGMII flag, indicating that the interface between
MAC and PHY is SGMII.

Add flags to specify whether internal delays should be configured for RGMII.

mii_softc's view of the current mii state need to use the proper types
(ifmedia64).

Make room for media types of the future. Extend the ifmedia word to 64 bits.
This changes numbers of the SIOCSIFMEDIA and SIOCGIFMEDIA ioctls and
grows struct ifmediareq.

Old ifconfig and dhclient binaries can still assign addresses, however
the 'media' subcommand stops working. Recompiling ifconfig and dhclient
with new headers before a reboot should not be necessary unless in very
special circumstances where non-default media settings must be used to
get link and console access is not available.

There may be some MD fallout but that will be cleared up later.

mii drivers no longer need activate functions. Repair of the PHY
configuration setting is done at resume time because all networks
drivers which were previously up, do an IFF_UP operation which
hits PHY_RESET.
