Subject: [RFC PATCH 18/21] DO_NOT_MERGE soc: build Foobar SoC drivers

Add Foobar SoC cache and memory controller drivers to the build.

The hypothetical Foobar SoC serves as an example of an SoC with
controllers that implement the RISC-V Capacity and Bandwidth QoS
Register Interface (CBQRI) specification.
