The EFI DT parameters for bare metal are located under /chosen node,
while for Xen Dom0 they are located under /hyperviosr/uefi node. These
parameters under /chosen and /hyperviosr/uefi are not expected to appear
at the same time.
Parse these EFI parameters and initialize EFI

ACPI 6.0 introduces a new table STAO to list the devices which are used
by Xen and can't be used by Dom0. On Xen virtual platforms, the physical
UART is used by Xen. So here it hides UART from Dom0.

Use xen_xlate_map_ballooned_pages to setup grant table. Then it doesn't
rely on DT or ACPI to pass the start address and size of grant table.

Xen: ACPI: Hide UART used by Xen
xen/grant-table: Move xlated_setup_gnttab_pages to commo
Move xlated_setup_gnttab_pages to common place, so it can be reused by
ARM to setup grant table.
Rename it to xen_xlate_map_ballooned_pages.
