Change 4787572d05 made if_alloc_domain() never fail, then also do the
wrappers if_alloc(), if_alloc_dev(), and if_gethandle().

Commit 4692906480 made e6000sw's
implementation of miibus_(read|write)reg assume that the softc lock is
held. I presume that is to avoid lock recursion in e6000sw_attach() ->
e6000sw_attach_miibus() -> mii_attach() -> MIIBUS_READREG().
However, the lock assertion in e6000sw_readphy_locked() can fail if a
different driver uses the interface to probe registers. Work around the
problem by providing implementations which lock the softc if it is not
already locked.

During attach we release the lock to call e6000sw_attach_miibus(), which
calls mii_attach(). The mii_attach() function calls miibus_readreg() /
miibus_writereg(). However, these are set to be
e6000sw_readphy_locked().
That is, the read/write phy functions do not acquire the lock, but
expect to be called while locked. Simply do not unlock and relock while
calling mii_attach().

When accessing a register directly from etherswitchcfg one must specify
a register group(e.g. registers of portN) and the register offset within
the group. The latter is passed as the 5 least significant bits.
Extract the former by dividing the register address by 32, not by 5.

Summary:
This switch is based off of the AR8327/AR8337 external switch/PHY.
However unlike the AR8327/AR8337 it itself doesn't have any PHYs;
instead an external PHY connects to it using the PSGMII port.

This code is inspired by the ar40xx code in openwrt, which itself
is based on the Qualcomm QCA-SSDK. Both of these sources are, amusingly,
BSD licenced - and thus I have included some of the comments in the
hardware workaround paths to document some of the magic numbers.
Remove unused file-local static function felix_phyforport()

Previously we would use an external MDIO device found on the PCI bus.
Switch to using MDIO mapped in a separate BAR of the switch device.
It is much easier this way since we don't have to depend on another

relation with the ethernet port of the SoC. Adjust
e6000sw etherswitch and mvneta drivers to that.
