This adds support for platform_battery driver which allows to specify a set
of power supply properties and callbacks to acquire them. It is needed to
support dumb batteries where all the information about their status can
only be obtained by platform-specific actions such as specific ADC
measurements, some guessimation etc.

This is the only user of the pcf50633 gpio api. Since the custom interface is
going to be replaced with gpiolib all users need to be remove or replaced.
It is safe to be remove it in this case since it is used used to turn a gpio
off which is never going to be turned on.

On the gta02 we often have a child parent relationship between different
devices. The child devices can only be probed after their parant has been.
Instead of adding a probe completed handler to each device we handle this in a
generic way with a bus notifier.

Early verions off uboot used for the gta02 flashed the nand with ecc information
incompatible to s3c2440 hardware ecc. Disable hardware error correction by
default, unless the bootloader explicitly enables it.

On hardware revision 5 and earlier the leds found on the gta02 are missing a
resistor and reading their gpio pin status will always return 0. So we have to
shadow the led states in software. This is done by "hijacking" the gpio accessor
functions for bank B.

The gta02 has three leds which are connected though gpio pins and thus can get
supported by using the generic leds-gpio driver.

The gta02 has two buttons which are connected to gpio pins and thus can get
supported by using the generic gpio-keys driver.

Move the pair of machines in arch/arm/mach-s3c2442 into the mach-s3c2440
directory as the S3C2440 and S3C2442 are very close.
