[PATCH 1/4] dt-bindings: mfd: brcm,cru: add clkset syscon

[Rafał Miłecki <zajec5@xxxxxxxxx>]

From: Rafał Miłecki <rafal@xxxxxxxxxx>

CRU has a shared register that is used e.g. to control USB 2.0 PHY block
access. It's a single 32 b register. Document it as syscon so it can be
used with a regmap.
