iommu/exynos: Add SysMMU v7 register set

Browse source

SysMMU v7 might have different register layouts (VM capable or non-VM
capable). Virtual Machine registers (if present) implement multiple
translation domains. If VM registers are not present, the driver
shouldn't try to access those.

Check which layout is implemented in current SysMMU module (by reading
the capability registers) and prepare the corresponding variant
structure for further usage.
