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".

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.
