net: dsa: mt7530: don't build GPIO support if !GPIOLIB
The new GPIO support may be optional at runtime, but it requires
building against gpiolib:
ERROR: modpost: "gpiochip_get_data" [drivers/net/dsa/mt7530.ko]
undefined!
ERROR: modpost: "devm_gpiochip_add_data_with_key"
[drivers/net/dsa/mt7530.ko] undefined!
Add #ifdef to exclude GPIO support if GPIOLIB is not enabled.
Fixes: 429a0edeefd8 ("net: dsa: mt7530: MT7530 optional GPIO support")
