Rather than refer to registers by number, define mnemonics. Also
define mnemonics for the commonly used bits within the registers.

The mv88e6171 can support two different tagging protocols, DSA and
EDSA. The switch driver structure only allows one protocol to be
enumerated, and DSA was chosen. However the Kconfig entry ensures the
EDSA tagging code is built. With a minimal configuration, we then end
up with a mismatch. The probe is successful, EDSA tagging is used, but
the switch is configured for DSA, resulting in mangled packets.
Change the switch driver structure to enumerate EDSA, fixing the
mismatch.

This change makes it so that instead of passing and storing a mii_bus we
instead pass and store a host_dev. From there we can test to determine the
exact type of device, and can verify it is the correct device for our switch.
So for example it would be possible to pass a device pointer from a pci_dev
and instead of checking for a PHY ID we could check for a vendor and/or device
ID.
