The original idea was to just avoid any update on register for pull up/down
configuration if this option is selected.
That doesn't sound correct. If a config option is specified in DT or the
mapping table, it should be applied to HW. If someone doesn't want a
particular config option applied, then it simply shouldn't be mentioned
in DT or the mapping table.
IIUC, BIAS_DEFAULT should be used only on HW where there is a concept of
a true default bias, and in that case, that is what should be applied.
Hmm.. When I added the PIN_DEFAULT, I just though that do not update
anything in the register and implemented like that.
There is nothing "default" option in HW.
In this patch, I just fixed the broken stuff due to recent change.
However, it the PIN_DEFAULT is not valid option then I need to remove it
from driver as well as from dt document of Palmas.
