pinctrl: renesas: r8a779f0: Fix GPIO function on I2C-capable pins
Unlike on R-Car Gen3 SoCs, setting a bit to zero in a GPIO / Peripheral
Function Select Register (GPSRn) on R-Car S4-8 is not always sufficient
to configure a pin for GPIO. For I2C-capable pins, the I2C function
must also be explicitly disabled in the corresponding Module Select
Register (MODSELn).
Add the missing FN_SEL_I2Ci_0 function enums to the pinmux_data[] array
by temporarily overriding the GP_1_j_FN function enum to expand to two
enums: the original GP_1_j_FN enum to configure the GPSR register bits,
and the missing FN_SEL_I2Ci_0 enum to configure the MODSEL register
bits.
