arm64/dma: Removing ARCH_HAS_DMA_GET_REQUIRED_MASK macro

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Arm64 does not define dma_get_required_mask() function.
Therefore, it should not define the ARCH_HAS_DMA_GET_REQUIRED_MASK.
This causes build errors in some device drivers (e.g. mpt2sas)
