Register Ether device from bockw_init(), passing the platform data to it, adding
only the RMII pin group to bockw_pinctrl_map[].  Although the LINK signal exists
on the board, it's connected to the link/activity LED  output of the PHY, thus
the link disappears and reappears after each packet. We'd be better off ignoring
such signal and getting the link state from the PHY indirectly.

underscore instead of hyphen.

KZM9G uses an AS3711 PMIC to supply power to the CPU and the LCD backlight.
The PMIC on the board is pre-programmed to supply correct voltages to the
CPU, power supply to the backlight has to be turned on at run-time. The
latter is currently performed by a hard-coded I2C command sequence in the
board file. This patch removes the backlight hack and instead adds an I2C
device to instantiate the AS3711 MFD driver, which will add a regulator
device to dynamically adjust CPU voltages and a backlight device.

As the kzm9d only has one smsc911x device it
may be registered as a platform device with id -1.

This allows the kzm9d board to access the smsc911x device
when CONFIG_REGULATOR (and CONFIG_REGULATOR_FIXED_VOLTAGE)
are set. The motivation for which is twofold: using regulators
seems to be generally a good thing; it will move the kzm9d defconfig
one step closer to being able to be consolidated with other
shmobile defconfigs.

An alternate but so far untested approach would be to
update the definition of dummy_supplies in board-kzm9d.c
to use "smsc911x.0" instead of "smsc911x".

An earlier commit "ARM: shmobile: sh73a0: add support for adjusting CPU

instead it replaced them for all div4 clocks, since all div4 clocks share

operations structure for Z-clock.

Allows us to boot with TWD only in the kernel configuration
for C board code. TWD is not yet enabled in the case of
DT -reference - this due to a dependency on CCF.
