Maxime Ripard 60242db1a7 pinctrl: sunxi: Add external interrupts support 
The port controller IP found in the Allwinner A10 and A13 can use few of
the pins it manage as an interrupt source, called external interrupts in
the datasheet.

The number of these external interrupts are SoCs specific, but the
current upper limit is 32. In order to work, the external interrupts'
pins have to be muxed to a specific function to generate an interrupt.

This patch adds the irqchip and the needed logic to use the PIO
controller as an interrupt controller.

* The sunXi PIO registers are organized as is:

* 8 pins per register, each pin having a 4bits value
* 0x10 Pin values
* 32 bits per register, each pin corresponding to one bit
* 0x14 - 0x18 Drive level
* 16 pins per register, each pin having a 2bits value
* 0x1c - 0x20 Pull-Up values
* 16 pins per register, each pin having a 2bits value
*
* This is for the first bank. Each bank will have the same layout,
* with an offset being a multiple of 0x24.
*
* The following functions calculate from the pin number the register
