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.
