ARM: plat-versatile: move FPGA irq driver to drivers/irqchip
This moves the Versatile FPGA interrupt controller driver, used in the Integrator/AP, Integrator/CP and some Versatile boards, out of arch/arm/plat-versatile and down to drivers/irqchip where we have consensus that such drivers belong. The header file is consequently moved to <linux/platform_data/irq-versatile-fpga.h>. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
