gpio: Fix the no return statement warning
In commit 242587616710 ("gpiolib: Add support for the irqdomain which doesn't use irq_fwspec as arg") we have changed the return type of gpiochip_populate_parent_fwspec_twocell/fourcell() from void to void *, but forgot to add a return statement for these two dummy functions. Add "return NULL" to fix the build warnings.
