Add a simple sandbox test for this uclass.
Signed-off-by: Simon Glass <sjg at chromium.org>
---
Changes in v5: None
Changes in v4:
- Drop itss uclass change in Makefile (now in previous patch)
- Drop sandbox defconfig change now that p2sb change is correct
- Enable IRQ for sandbox64 too to avoid build error
Changes in v3:
- Change the sandbox test from ITSS to IRQ
Changes in v2: None
