Geert Uytterhoeven 587a9b5dad pinctrl: sh-pfc: emev2: Use new macros for non-GPIO pins
Update the EMMA Mobile EV2 pin control driver to use the new macros for
describing pins without GPIO functionality.  This replaces the use of
physical pin numbers on the EMMA Mobile EV2 SoC (in 23x23 BGA 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.

Geert Uytterhoeven 69f7be1c63 pinctrl: sh-pfc: Absorb enum IDs in PINMUX_CFG_REG_VAR() macro
Currently the PINMUX_CFG_REG_VAR() macro must be followed by
initialization data, specifying all enum IDs.  Hence the macro itself
does not know anything about the enum IDs, preventing the macro from
performing any validation on it.

Make the macro accept the enum IDs as a parameter, and update all users.
Note that array data enclosed by curly braces cannot be passed to a
macro as a parameter, hence both the register field widths and the enum
IDs are wrapped using the GROUP() macro.

No functional changes.

Geert Uytterhoeven 1ecd8c9cb8 pinctrl: sh-pfc: emev2: Add missing pinmux functions
The err_rst_reqb, ext_clki, lowpwr, and ref_clko pin groups are present,
but no pinmux functions refer to them, hence they can not be selected.

Geert Uytterhoeven b8b47d678a pinctrl: sh-pfc: Rename .gpio_data[] to .pinmux_data[]
The sh_pfc_soc_info.gpio_data[] array contains not only GPIO data, but
also various other pinmux-related data (functions and marks).
Every single driver already calls its local array pinmux_data[].
Hence rename the sh_pfc_soc_info member to "pinmux_data".
