Wu Zhangjin f1df323924 MIPS: Loongson-2F: Flush the branch target history in BTB and RAS 
As per chapter 15 "Errata: Issue of Out-of-order in loongson"[1] to work
around the Loongson 2F erratum we need to do:

"When switching from user mode to kernel mode, you should flush the
branch target history such as BTB and RAS."
