If the driver is going to select a single state ("sdhci-pcfg8" or
"sdhci-pcfg4" above) at probe() time and never change it (which seems
quite reasonable for an SDHCI controller), then the driver should always
use state PINCTRL_STATE_DEFAULT, and it should be up to the board to set
up the mapping table such that PINCTRL_STATE_DEFAULT sets up the pins
for either 4-bit or 8-bit as appropriate for the board.
