pinctrl: ocelot: fix gpio direction for pins after 31 

The third argument passed to REG is not the correct one and
ocelot_gpio_set_direction is not working for pins after 31. Fix that by
passing the pin number instead of the modulo 32 value.

Fixes: da801ab56a pinctrl: ocelot: add MSCC Jaguar2 support
