Add JAILHOUSE_IOMMU_ARM_MMU500 to the Jailhouse iommu type. Add
arm_sid_mask to struct jailhouse_iommu, and it is a mask of StreamID
bits irrelevant to the matching process.

This should go into the union as
struct {
__u32 sid_mask;
} __attribute__((packed) mmu500; (or arm_mmu400)
That's because no other IOMMU will have a use for this parameter. The
packed is unneeded at this stage, just for consistency.
