intelblocks/gpio.c: Handle NULL return values from child functions
gpio_configure_pad function gets called for most of the GPIO configuration for all the boards. This function is not handling NULL pointers properly which can cause exception in CPU. This patch fixes the handling and function is able to return early in case the NULL pointer is passed or any subsequent child function calls return NULL. BUG=None BRANCH=None TEST=Compilation works fine for all Alder Lake boards.
