Gerard Marull-Paretas 442fae1b38 drivers: pinctrl: fix lookup when there are no states 
Right now it is possible that some devices define 0 pinctrl states in
devicetree, because pinctrl-N entries may still be optional for backward
compatibility. If the programmer makes a mistake and forgets them,
application could experience runtime crashes because
pinctrl_lookup_states assumes you have at least one state, so it does
not perform any bounds checking. Change the while condition so that it
is skipped if states count is zero.
