ARM: dma-mapping: don't allow DMA mappings to be marked executable

commit 0ea1ec713f04bdfac343c9702b21cd3a7c711826 upstream.

DMA mapping permissions were being derived from pgprot_kernel directly
without using PAGE_KERNEL.  This causes them to be marked with executable
permission, which is not what we want.  Fix this.
