[PATCH v4 resend v4 4/6] ArmPlatformPkg/ArmJunoDxe: don't register OnEndOfDxe event on rev R0

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

The ArmJunoDxe driver code registers a callback for the EndOfDxe event,
at which time it does some manipulation of the PCI peripherals on the
board. Given that R0 has no working PCIe, instead of conditionally
performing these operations, omit the registration of the
callback altogether on that platform.
