Revert "Revert "arm64: dma: Drop cache invalidation from arch_dma_prep_coherent()""
This reverts commit b7d9aae404841d9999b7476170867ae441e948d2.
With the Qualcomm remoteproc driver now modified to use a carveout
memory region in 57f72170a2b2 ("remoteproc: qcom_q6v5_mss: Use a
carveout to authenticate modem headers"), we can reinstate c44094eee32f
("arm64: dma: Drop cache invalidation from arch_dma_prep_coherent()")
which relaxes the arm64 implementation of arch_dma_prep_coherent() to
perform only a data cache clean operation, rather than a
clean-and-invalidate.
