arm64: Make DMA coherent and strongly ordered mappings not executable
commit de2db7432917a82b62d55bb59635586eeca6d1bd upstream.
pgprot_{dmacoherent,writecombine,noncached} don't need to generate
executable mappings with side-effects like __sync_icache_dcache() being
called when the mapping is in user space.
