ivshmem: Expand MSI-X region to full page
It's a bit wasteful, but the alternative can be that the guest moves the
region close to a physical one, and then we need to start configuring
sub-page dispatching. That is first of all a source for mistakes
(specifically in combination with generated configs), and it may even be
suboptimal in case exceeding, full-page access on that physical region
would have been safe.

Introduce an iterator macro for this. Helps to simplify the code.

Still a net gain as a lot of boilerplate code can be dropped.
Along this cleanup, convert arm_smmu_s2cr_type and arm_smmu_s2cr_privcfg
into defines, only encoding what we use. There is no value in enums.

arm64: smmu: Fix CBn_TCR initialization
This was simply wrong: We must use the same settings for the SMMU as for
the MMU because we share the page tables. We can pick up VTCR_CELL for
this, just like SMMUv3 does, we just need to mask out reserved bits.
