This is a slightly trickier case as there's pca953x_gpio.c that is
DM_GPIO, so the question is if we have cases where SPL_DM is off (SPL_DM
is not required) and so the platform cannot switch over to the DM
driver there, but needs to for full U-Boot.  Maybe we need a new symbol,
CONFIG_SPL_PCA953X that depends on !SPL_DM_GPIO.
