dt-bindings: mfd: Document control-scb and sysreg-scb on pic64gx

ConchuOD · lag-linaro · commit 1f9793a4d518 · 2025-11-20T14:16:27.000Z
On pic64gx these syscons are identical to those on mpfs, and should use a fallback. Add support for multiple fallback compatibles to syscon.yaml with these as the first two users.
