Since this macro is identical to pgprot_writecombine() and is only used in a single place, remove it completely to avoid confusion. On ARMv7+ processors, the coherent DMA mapping must be Normal NonCacheable (a.k.a. writecombine) to avoid mismatched hardware attribute aliases (with the kernel linear mapping as Normal Cacheable).
