Yong Wu 2713fe3715 Revert "iommu/io-pgtable-arm: Check for v7s-incapable systems" ...

This reverts commit 82db33dc5e.

After the commit 29859aeb8a ("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.
