ArmVirtualizationPkg: allow patchable PCD for device tree base address
To allow a runtime self relocating PrePi instance to discover the base
address of the device tree at runtime, allow the use of a patchable PCD
for gArmVirtualizationTokenSpaceGuid.PcdDeviceTreeInitialBaseAddress.
We will not be using the build time patch tool in this case, but using
a patchable PCD will make the build system aware that its value is not
a compile time constant.
