fa84f89395e0 ("irqchip/loongson-liointc: Fix build error for
LoongArch") replaced get_ebase_cpunum with physical processor
id from SMP facilities. However that breaks MIPS non-SMP build
and makes booting from other cores inpossible on non-SMP kernel.
Thus we revert get_ebase_cpunum back and use get_csr_cpuid for
LoongArch.
