MIPS: cacheflush: Use __flush_icache_user_range()

The cacheflush(2) system call uses flush_icache_range() to flush a range
of usermode addresses from the icache, so change it to utilise the new
__flush_icache_user_range() API to allow the more generic
flush_icache_range() to be changed to work on kernel addresses only.
