gpio: zynq: Do PM initialization earlier to support gpio hogs
GPIO hogs registration is call at the end of gpiochip_add() function. Calling sequence is: gpiochip_add -> of_gpiochip_add -> of_gpiochip_scan_hogs -> gpiod_hog -> gpiochip_request_own_desc -> __gpiod_request -> chip->request -> zynq_gpio_request which calls pm_runtime_get_sync() which returns -13 because PM is not initialized yet. Initialize PM before gpiochip_add is called to fix this issue.
