[PATCH] Platforms/ARM/Juno: limit ACPI support to v5.0 and higher

[Sudeep Holla]

The ACPI spec predates the AARCH64 architecture by 5 versions, so there
is no point in supporting anything below v5.0. So set the PCD that
controls the ACPI table generation to the appropriate value.

Based on the commit e0692789058e ("ArmVirtPkg/ArmVirtQemu: limit ACPI
support to v5.0 and higher") in the upstream TianoCore by Ard Biesheuvel
