This driver adds support the Cortex-A9 based SoCs from Rockchip,
so at least the RK2928, RK3066 (a and b) and RK3188.
Earlier Rockchip SoCs seem to use similar mechanics for gpio
handling so should be supportable with relative small changes.
Pull handling on the rk3188 is currently a stub, due to it being
a bit different to the earlier SoCs.
Pinmuxing as well as gpio (and interrupt-) handling tested on
a rk3066a based machine.

The ARM GIC binding defines a few custom cells and flags for its IRQ
specifier. Provide names for those.

Many IRQ device tree bindings use the same flags. Create a header to
define those.
