pinctrl: sh-pfc: r8a7791: Add missing DVC_MUTE signal

commit 3908632fb829d73317c64c3d04f584b49f62e4ae upstream.

The R8A7791 PFC driver  was apparently based on the preliminary revisions
of  the user's  manual, which  omitted the DVC_MUTE signal  altogether in
the PFC section. The modern manual has the signal described,  so just add
the necassary data to the driver...
