Shrink sh_pfc_pin_config from 8 to 2 bytes:
- The mux_set flag can be removed, as a non-zero mark value means the
same (zero = PINMUX_RESERVED is an invalid mark value),
- The gpio_enabled flag needs only a single bit,
- Mark values are small integers, and can easily fit in a 15-bit
bitfield.
This saves 6 bytes per pin when allocating the sh_pfc_pinctrl.configs
array, i.e. it reduces run-time memory consumption by ca. 1.5 KiB.
