Platforms/ARM/Juno: move to unicore PrePi
Move to the unicore PrePi implementation. This is possible, since we only
support executing under ATF anyway, so only the boot CPU enters UEFI in
EL2, and booting multiple cores using the ARM_MP_CORE protocol is only
supported when using the LinuxLoader.
The reason we need to make this change is because Juno implements this
protocol using 32-bit wide mailbox registers, which is awkward on an
otherwise 64-bit architecture, and this is holding back progress for
other platforms that need to implement the ACPI parking protocol.
