[MIPS] Define MIPS_CPU_IRQ_BASE in generic header The irq_base for {mips,rm7k,rm9k}_cpu_irq_init() are constant on all platforms and are same value on most platforms (0 or 16, depends on CONFIG_I8259). Define them in asm-mips/mach-generic/irq.h and make them customizable. This will save a few cycle on each CPU interrupt. A good side effect is removing some dependencies to MALTA in generic SMTC code. Although MIPS_CPU_IRQ_BASE is customizable, this patch changes irq mappings on DDB5477, EMMA2RH and MIPS_SIM, since really customizing them might cause some header dependency problem and there seems no good reason to customize it. So currently only VR41XX is using custom MIPS_CPU_IRQ_BASE value, which is 0 regardless of CONFIG_I8259. Testing this patch on those platforms is greatly appreciated. Thank you.
