[PATCH 3/3] net: dsa: mt7530: add GPIOLIB dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

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 a Kconfig dependency to enforce this.

Fixes: 429a0edeefd8 ("net: dsa: mt7530: MT7530 optional GPIO support")
