pinctrl-coh901 driver already uses PIN_CONFIG_BIAS_DISABLE without argument.

I think that it's better to use both BIAS_ENABLE & BIAS_DISABLE. Otherwise,
I need to update pinctrl-coh901 driver with updating the interface.
The work is a little
large.

Maybe we can use another name, PIN_CONFIG_BIAS_AUTOPULL. Then we can
distinguish it from PULL_UP & PULL_DOWN without any confusion. What's your
opinion?
