gpio: mt7621: pass mediatek_gpio_bank_probe() failure up the stack

Browse source

[ Upstream commit a109c2dbb5 ]

The error cases of mediatek_gpio_bank_probe() would go unnoticed (except
for the dev_err() messages). The probe function should return an error
if one of the banks failed to initialize properly indicated by
not returning non-0.
