Revert "iommu/io-pgtable-arm: Check for v7s-incapable systems"
This reverts commit 82db33dc5e49fb625262d81125625d07a0d6184e.
After the commit 29859aeb8a6e ("iommu/io-pgtable-arm-v7s: Abort
allocation when table address overflows the PTE"), v7s will return fail
if the page table allocation isn't expected. this PHYS_OFFSET check
is unnecessary now.
And this check may lead to fail. For example, If CONFIG_RANDOMIZE_BASE
is enabled, the "memstart_addr" will be updated randomly, then the
PHYS_OFFSET may be random.
