ArmVirtualizationPkg: use a HOB to store device tree blob
Instead of using a dynamic PCD, store the device tree address in a HOB
so that we can also run under a configuration that does not support
dynamic PCDs.
This also adds MemoryAllocationLib to the [LibraryClasses] section of
ArmVirtualizationPlatformLib/ArmVirtualizationPlatformLib.inf, as this
dependency was formerly satisfied transitively through one of the
library dependencies that were dropped.
