acpi: arm/virt: madt: bump to revision 4 accordingly to ACPI 6.0 Errata A
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")
