powerpc/sysdev/simple_gpio: Fix oops in gpio save_regs function
of_mm_gpiochip_add_data() generates an oops for NULL pointer dereference.
of_mm_gpiochip_add_data() calls mm_gc->save_regs() before
setting the data, therefore ->save_regs() cannot use gpiochip_get_data()
Fixes: 937daafca774 ("powerpc: simple-gpio: use gpiochip data pointer")
