pinctrl: sh-pfc: r8a7790: Use new macros for non-GPIO pins

Browse source 
Update the R-Car H2 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 H2 SoC (in 31x31 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.
