Presently fastmap iommu feature allocates page tables for
full 4GB virtual address space. This can be optimized to
consider virtual address range [base, size] needed by
client and prepare page tables only for applicable
region.

[@lmark@codeaurora.org: modify downstream struct instead]
Signed-off-by: Liam Mark <lmark@codeaurora.org>
Fastmap uses the same page table format as arm_lpae_s1_cfg,
so they can share the same data structure format. Additionally,
arm-smmu.c *assumes* that struct arm_lpae_s1_cfg is in use.
This has not caused any issues so far because the formats of
av8l_fast_cfg and arm_lpae_s1_cfg are sufficiently similar.

Fix up a bunch of headers so that they pass KERNEL_HEADER_TEST to ensure
that they are self-contained.
