4be1eaf322 pinctrl: nuvoton: check for devm_kasprintf() failure 
devm_kasprintf() may return NULL on failure of internal allocation thus
the assignment to  .label  is not safe if not checked. On error
npcm7xx_gpio_of() returns negative values so -ENOMEM in the
(unlikely) failure case of devm_kasprintf() should be fine here.
