Fingerprint: fix potential null pointer dereference issue



The pointer of two-dimensional array which may cause some
null pointer dereference. eg..fpc1020->pinctrl_state[1] is
not initialized by default, although fpc1020->pinctrl_state
is initialized by default. Use one dimensional array pointer
to fix the issue.
