core: Introduce struct jailhouse_iommu

For AMD, we need to store not only base address but also MMIO size
(and maybe other attributes in future). Introduce struct jailhoue_iommu
to encapsulate all data required. For now, all fields make sense both for
VT-d and AMD IOMMU.

pci: Add pci_find_capability_by_id()

Implement a way to get capability block by the identifier.
This is essential for PCI devices configuration from the hypervisor,
e.g. in amd_iommu code.

x86: Prepare to introduce amd_iommu code

Add few modifications to Jailhouse codebase required for amd_iommu code
to work properly. First, we allocate IOMMU page tables statically in
struct cell. Second, account for page sizes larger than 2GB in struct paging.

x86: Add amd_iommu page tables handling code

amd_iommu page tables are extensions to x86_64 page tables. However,
they are 6-level, so one can't easily derive them from x66_64_paging
structures, as e.g. SVM code does.

This commit adds self-containing amd_iommu_paging structures.

to submit commands to AMD IOMMU command buffer. For now, having only
INVALIDATE_IOMMU_PAGES and COMPLETION_WAIT seems to be sufficient.

x86: Add device management functions for amd_iommu

Implement iommu_add_pci_device() for amd_iommu.

Basically, this is all about filling DTE entry. However, there is no way
to allocate device tables sparsely with ADM IOMMU. To save some memory,
Device Table Segmentation (Revision 2.6 and up) is used whenever possible,
and this adds some infrastructure.

Add functions to read event logs AMD IOMMU provides and print their
contents. The latter is rather basic, but decoding all possible log
entries is hairy, so we'd better wait and collect stats which
problems occur most often.

Add iommu_pending_faults() for amd_iommu. This looks into
Hardware Event Register first, and then loops over the event log
printing what's in it. This way, we don't miss errors that happen
when event logging is unavailable.
