iommu/exynos: Enable default VM instance on SysMMU v7
In order to enable SysMMU v7 with VM register layout, at least the
default VM instance (n=0) must be enabled, in addition to enabling the
SysMMU itself. To do so, add corresponding write to MMU_CTRL_VM[0]
register, before writing to MMU_CTRL register.
