[PATCH 3/3] clk: shmobile: rz: Document mandatory compatible fallback

[Geert Uytterhoeven <geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org>]

The generic RZ CPG compatible value is mandatory, as the driver uses
only this value for matching.  Document that this is a fallback that
must be present.
