The AXP223 is a new PMIC commonly paired with Allwinner A23/A33 SoCs.
It is functionally identical to AXP221; only the regulator default
voltage/status and the external host interface are different.

The axp20x driver assumes the device is i2c based. This is not the
case with later chips, which use a proprietary 2 wire serial bus
by Allwinner called "Reduced Serial Bus".
This patch follows the example of mfd/wm831x and splits it into
an interface independent core, and an i2c specific glue layer.
MFD_AXP20X and the new MFD_AXP20X_I2C are changed to tristate
symbols, allowing the driver to be built as modules.
Included but unused header files are removed as well.

The AXP223 is a new PMIC commonly paired with Allwinner A23/A33 SoCs.
It is functionally identical to AXP221; only the regulator default
voltage/status and the external host interface are different.

Some boards, such as tablets, have regulators providing power to parts
of the display pipeline, like signal converters and LCD panels.
Add labels to the simplefb device nodes so that we can reference them
in the board dts files to add regulator supply properties.

axp20x support has been split into 2 parts, I2C and RSB interface
variants.
Update the MFD_AXP20X symbol for I2C support, and also enable
MFD_AXP20X_RSB to support RSB variants.
Keep MFD_AXP20X enabled for now, to ease migration for automated boot
farms while the patches are being merged. This should be removed in the
next release.

Update the MFD_AXP20X symbol for I2C support. Also enable SUNXI_RSB
MFD_AXP20X_RSB to support RSB variants. Build these drivers as
modules.
