irqchip/loongson: Select GENERIC_IRQ_EFFECTIVE_AFF_MASK if SMP for IRQ_LOONGARCH_CPU
An interrupt's effective affinity can only be different from its configured affinity if there are multiple CPUs. Make it clear that this option is only meaningful when SMP is enabled. Otherwise, there exists "WARNING: unmet direct dependencies detected for GENERIC_IRQ_EFFECTIVE_AFF_MASK" when make menuconfig if CONFIG_SMP is not set on LoongArch.
