Subject: [PATCH 5.1 26/54] pinctrl: ocelot: fix gpio direction for pins after 31

[ Upstream commit f2818ba3a0125670cb9999bb5a65ebb631a8da2f ]

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: da801ab56ad8 pinctrl: ocelot: add MSCC Jaguar2 support
