Subject: [PATCH 5.4 171/261] MIPS: CPU_LOONGSON2EF need software to maintain cache consistency

From: Lichao Liu <liulichao@...ngson.cn>

commit a202bf71f08b3ef15356db30535e30b03cf23aec upstream.

CPU_LOONGSON2EF need software to maintain cache consistency,
so modify the 'cpu_needs_post_dma_flush' function to return true
when the cpu type is CPU_LOONGSON2EF.
