gpio: mpc8xxx: Add platform device to gpiochip->parent [ Upstream commit 322f6a3182d42df18059a89c53b09d33919f755e ] Dear Linus Walleij, In old kernels, some APIs still try to use parent->of_node from struct gpio_chip, and it could be resulted in kernel panic because parent is NULL. Adding platform device to gpiochip->parent can fix this problem.
