The MADT table structure has been updated in commit 37f33084ed2e                 
("acpi: arm/virt: madt: use build_append_int_noprefix() API to compose MADT table")
to include the 5.2.12.18 GIC ITS Structure and so table's revision also needs to 
be updated. MADT and the FADT tables from the same spec need to be in sync and in
this case also the FADT needs to be updated.                                     

Revision 6.0 of the ACPI FADT table introduces the field "Hypervisor Vendor      
Identity" which is missing and must be included.

This patch series originates from a previous RFC [1] discussion. Reviewed-by
tags were kept on patches 2/4 and 3/4.

Update the Fixed ACPI Description Table (FADT) to revision 6.0 of the ACPI
specification adding the field "Hypervisor Vendor Identity".

This field's description states the following: "64-bit identifier of hypervisor
vendor. All bytes in this field are considered part of the vendor identity.
These identifiers are defined independently by the vendors themselves,
usually following the name of the hypervisor product. Version information
should NOT be included in this field - this shall simply denote the vendor's
name or identifier. Version information can be communicated through a
supplemental vendor-specific hypervisor API. Firmware implementers would
place zero bytes into this field, denoting that no hypervisor is present in
the actual firmware."

MADT has been updated with the GIC Structures from ACPI 6.0 Errata A
and so MADT revision and GICC Structure must be updated also.

Fixes: 37f33084ed2e ("acpi: arm/virt: madt: use build_append_int_noprefix() API to compose MADT table")
