[PATCH v2 7/9] target/loongarch: Use mmu idx bitmap method when flush tlb

[Bibo Mao]

With API tlb_flush_range_by_mmuidx(), bitmap method of mmu idx should
be used rather than itself. Also mmu idx comes from page table entry
information rather current running mode. With page table entry,
global bit for MMU_KERNEL_IDX, otherwise it is MMU_USER_IDX.
