gpio: mpc8xxx: Do not use gpiochip_get_data() in mpc8xxx_gpio_save_regs()
Commit709d71a17c
("gpio: mpc8xxx: use gpiochip data pointer") replaces the use of container_of() with gpiochip_get_data(). However, the data pointer is not yet set by the time the save_regs function is called. Fixes:709d71a17c
