Rename the dynamic replicator specific routines for merging with the
replicator driver. Also re-arrange the probe routine to make it easier
to merge.

As we are about to about refactor the platform specific handling,
move the DT property handling to generic helpers.

The stimulus base for STM device must be listed as the second memory
resource, followed by the programming base address. Add support for
parsing the information for ACPI.

So far we have hard coded the DT platform parsing code in
every driver. Introduce generic helper to parse the information
provided by the firmware in a platform agnostic manner, in preparation
for the ACPI support.
