The macro REG gets defined in at least two locations -
drivers/pinctrl/pinctrl-ocelot.c and include/soc/mscc/ocelot.h. While
pinctrl-ocelot.c doesn't include include/soc/mscc/ocelot.h, it does in fact
include include/linux/mfd/ocelot.h.
This was all fine, until include/linux/mfd/ocelot.h needed resources from
include/soc/mscc/ocelot.h. At that point the REG macro becomes redefined,
and will throw a compiler error.
Undefine the REG macro in drivers/pinctrl/pinctrl-ocelot.c before it is
defined to avoid this error.
