pinctrl: renesas: rmobile: Mark unused PORTCR bits reserved
The PULMD bits and the SEC bit in the PORTCR register descriptions on
SH/R-Mobile SoCs are either unused or unsupported. Describe them as
reserved bits using a negative field width value, and drop the
corresponding dummy enum IDs.
This reduces kernel size by 2832 (R-Mobile APE6), 2544 (R-Mobile A1),
and/or 3228 (SH-Mobile AG5) bytes.
