[PATCH] MIPS: ath79: irq: Remove the include of drivers/irqchip/irqchip.h

[Alban Bedel <albeu@free.fr>]

We shouldn't include irqchip.h from outside of the drivers/irqchip
directory. The irq driver should idealy be there, however this not
trivial at the moment. We still need to support platforms without DT
support and the interface to the DDR controller still use a custom
arch specific API.

For now just redefine the IRQCHIP_DECLARE macro to avoid the cross
tree include.
