This adds a model of the nRF51 GPIO peripheral.
Reference Manual: http://infocenter.nordicsemi.com/pdf/nRF51_RM_v3.0.pdf
The nRF51 series microcontrollers support up to 32 GPIO pins in various configurations.
The pins can be used as input pins with pull-ups or pull-down.
Furthermore, three different output driver modes per level are
available (disconnected, standard, high-current).
The GPIO-Peripheral has a mechanism for detecting level changes which is
not featured in this model.

This adds the BCM2835 GPIO controller.
It currently implements:
- The 54 GPIOs as outputs (qemu_irq)
- The SD controller selection via alternate function of GPIOs 48-53

Tracked down with an ugly, brittle and probably buggy Perl script.
Also move includes converted to <...> up so they get included before
ours where that's obviously okay.

The i.MX6 GPIO device supports 2 interrupts instead of one.
* 1 for the lower 16 GPIOs.
* 1 for the upper 16 GPIOs.
i.MX31 and i.MX25 only support 1 interrupt for the 32 GPIOs.
So we add a property to turn the behavior on when required.
