gpio: zynq: fix runtime PM leak on remove

pm_runtime_get_sync() increments the runtime PM usage counter even when it
returns an error. zynq_gpio_remove() uses it to keep the controller active
while removing the GPIO chip, but never drops the usage counter again.

Balance the get with pm_runtime_put_noidle() after disabling runtime PM.
