Subject: [PATCH v2 1/3] MIPS: JZ4740: Break circular header dependency

When including irq.h, arch/mips/jz4740/irq.h will be selected as the
first candidate. This header does not include the proper definitions
(most notably NR_IRQS) required by subsequent headers. To solve this
arch/mips/jz4740/irq.h can be deleted and its contents can be moved
into arch/mips/include/asm/mach-jz4740/irq.h, which will then be
correctly included.
