With this patch, the bq24022 battery charger is controlled by the USB
gadget framework (via gpio_vbus) when connected to USB.
To compile, this patch depends on the "regulator: Allow init data to be
supplied for bq24022" patch (queued for next in the regulator tree) to
add the init_data field to struct bq24022_mach_info.
It also depends on the "add optional OTG transceiver and voltage
regulator support to pda_power" patch (queued for next in the power
supply tree) to enable charging when connected to the AC charger.

Some Phytec cameras have a I2C GPIO expander which allows it to
switch between different sensor bus widths. This was previously
handled in the camera driver. Since handling of this switch
varies on several boards the cameras are used on, the board
support seems a better place to handle the switch

2. common code in <mach/gpio.h> moved into <plat/gpio.h>, new processors
should implement its own <mach/gpio.h>, provide the following required

- GPIO_REGS_VIRT for mapped virtual address of the GPIO registers'
physical I/O memory
- macros of GPLR(), GPSR(), GPDR() for constant optimization for

OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not. There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().
This patch fixes things to pass this string to arch_reset(). This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

The remaining registers are separated into:
- <mach/regs-ost.h>
- <mach/regs-rtc.h>
- <mach/regs-intc.h>
and then we can remove pxa-regs.h completely. Instead of #include this
file, let's:
1. include the specific <mach/regs-*.h> with care (if that's absolutely
necessary)
2. define the registers in the driver, make cleanly defined API to expose
the register access to external with sufficient reason

2. 'struct pxa_gpio_chip' is expanded to include IRQ edge and mask

3. all accesses to GPIO registers are made through 'regbase' within
