Set the default value of PcdAcpiExposedTableVersions for Aarch64 platforms to 0x20. Previously, the default was set to 0x3E for all platforms. The new value removes ACPI 1.0b compatability, which forces the use of XSDT 64-bit pointer, as required by Arm SBBR specification. This also resolves an error reported by acpiview command, as seen on the RPi (see https://github.com/pftf/RPi4/issues/25).
