[PATCH] iommu/io-pgtable-arm: Remove split on unmap behavior

[Daniel Mentz]

With the removal of arm_lpae_split_blk_unmap, I believe the following
macros are now unused. Is there any interest in removing those as
well? If so, I can draft a patch.

#define ARM_LPAE_PTE_ATTR_LO_MASK (((arm_lpae_iopte)0x3ff) << 2)
/* Ignore the contiguous bit for block splitting */
#define ARM_LPAE_PTE_ATTR_HI_MASK (ARM_LPAE_PTE_XN | ARM_LPAE_PTE_DBM)
#define ARM_LPAE_PTE_ATTR_MASK (ARM_LPAE_PTE_ATTR_LO_MASK | \
ARM_LPAE_PTE_ATTR_HI_MASK)
#define iopte_prot(pte) ((pte) & ARM_LPAE_PTE_ATTR_MASK)
