Subject: [PATCH] arm64/dma: Removing ARCH_HAS_DMA_GET_REQUIRED_MASK macro

From: Suravee Suthikulpanit <[email protected]>

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)
