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.
