Per the ACPI 6.5 specification, on the GTDT Table Structure, the Counter Control
Block Address and Counter Read Block Address fields of the GTDT table should be
set to 0xFFFFFFFFFFFFFFFF if not provided, rather than 0x0.
Fixes: 41041e57085 ("acpi: arm/virt: build_gtdt: use
acpi_table_begin()/acpi_table_end() instead of build_header()")
