Add Lee - My apologies, it seems like you got a new email address and I
didn't copy it on this series.

The VSC7512 is a networking chip that contains several peripherals. Many of
these peripherals are currently supported by the VSC7513 and VSC7514 chips,
but those run on an internal CPU. The VSC7512 lacks this CPU, and must be
controlled externally.

Utilize the existing drivers by referencing the chip as an MFD. Add support
for the two MDIO buses, the internal phys, pinctrl, and serial GPIO.

v16
    * Includes fixups:
    *  ocelot-core.c add includes device.h, export.h, iopoll.h, ioport,h
    *  ocelot-spi.c add includes device.h, err.h, errno.h, export.h, 
       mod_devicetable.h, types.h
    *  Move kconfig.h from ocelot-spi.c to ocelot.h
    *  Remove unnecessary byteorder.h

Something is going on that I don't fully understand with <asm/byteorder.h>.
I don't quite see how ocelot-core is throwing all sorts of errors in x86
builds now:

Snippet from there:

<asm/byteorder.h> was included in both drivers/mfd/ocelot-spi.c and
drivers/mfd/ocelot.h previously, though Andy pointed out there didn't
seem to be any users... and I didn't either. I'm sure there's something
I must be missing.

    * Utilize resource_size() function
