Introduce a common structure to hold the fw (ACPI or DT) defined
configuration for SMMU hw. The current use case is for arm SMMUs. So,
making this architecture specific.

Modify the SMMU code to use generic device instead of dt_device_node for
functions that can be used for ACPI based systems too.

The load restriction placed in the above reverted patch resulted in a crash
when booting DOM0 on a Qualcomm platform with non contiguous system RAM.
(XEN) DOM0: [ 0.00] bootmem alloc of 64 bytes failed!
(XEN) DOM0:
This reverts commit db92b1ac55cd5e193ae22b0b6f01fb47bc9e5d2f.
There does not seem to be a restriction on non contiguous memory anymore . So,
reverting this change, so that Xen is placed at the end of the useable
system RAM even if the partitions are not contiguous.
