[PATCH 2/2] dt-bindings: mfd: document syscons falling back to atmel,sama5d2-sfrbu

From: Conor Dooley <conor.dooley at microchip.com>

The sfrbu on both sama7g5 and sama6d65 both fall back to sama5d2 in
devicetrees, but the former two compatibles were undocumented. Now that
syscon.yaml has easy support for multiple soc-specific compatibles, add
both of these undocumented devices.
