hw/intc/loongson: Fix incorrect 'core' calculation in liointc_read/write
According to the loongson spec
(http://www.loongson.cn/uploadfile/cpu/3B1500/Loongson_3B1500_cpu_user_1.pdf)
and the macro definition(#define R_PERCORE_ISR(x) (0x40 + 0x8 * x)), we know
that the ISR size per CORE is 8, so here we need to divide
(addr - R_PERCORE_ISR(0)) by 8, not 4.
