[PATCH v3 3/3] dt-bindings: clock: mpfs-clkcfg: Add pic64gx compatibility

[Conor Dooley <conor@kernel.org>]

From: Pierre-Henry Moussay <pierre-henry.moussay@microchip.com>

pic64gx has a clock controller compatible with mpfs-clkcfg. Don't permit
the deprecated configuration that was never supported for this SoC.
