Either is fine - do whatever makes most sense for your system.

This is the common situation for SoC CPUs - most silicon vendors reuse
the same IPs in diffierent combinations on different CPUs.  The normal
approach is to have the generic code for each SoC set up the resources
for the devices that are present on that particular SoC.  This avoids
the need for each board using the SoC to have to replicate the
