MIPS: EMMA2RH: Remove EMMA2RH_CPU_CASCADE

Although all EMMAxxx SoCs can support IP2 and IP3 hardware interrupts,
current EMMA2RH plat_irq_dispatch() supports IP2 only.  We can make it
configurable in the future, but for the time being, would like to make
things explicitly allcated to IP2 in accordance with plat_irq_dispatch().
