Revert "pinctrl: sh-pfc: r8a77990: Add support for pull-up only pins"
This reverts commit f4caa6ee736fa8a46c806ba4382c16f7e5a20248.
The same can be expressed better by dropping the
SH_PFC_PIN_CFG_PULL_DOWN flag from the GPIO description, as it includes
returning an error to the caller when trying to configure the pin for
pull-down, causing:
sh-pfc e6060000.pin-controller: pin_config_set op failed for pin 201
sh-pfc e6060000.pin-controller: Error applying setting, reverse things back
sh-pfc e6060000.pin-controller: failed to select default state
