pinctrl: coh901: add device tree support
This makes it possible to probe the COH901 pinctrl driver from the device tree, and assigned the device tree node in the gpio_chip so we can look up cross-references from the device tree. Start grabbing the per-port (bank) IRQs by index instead of by name so we don't have to look up the IRQs by name going forward. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
