MIPS: KVM: Use local_flush_icache_range to fix RI on XBurst
MIPS KVM uses mips32_SyncICache to synchronise the icache with the dcache after dynamically modifying guest instructions or writing guest exception vector. However this uses rdhwr to get the SYNCI step, which causes a reserved instruction exception on Ingenic XBurst cores. It would seem to make more sense to use local_flush_icache_range() instead which does the same thing but is more portable.
