pinctrl: sh-pfc: r8a7778: Use new macros for non-GPIO pins
Update the R-Car M1A pin control driver to use the new macros for describing pins without GPIO functionality. This replaces the use of physical pin numbers on the R-Car M1A SoC (in 25x25 FCBGA package) by symbolic enum values, referring to signal names. Note that the user-visible names of these pins are still based on pin numbers instead of signal names, to preserve DT backwards compatibility.
