pinctrl: armada-37xx: use correct OUTPUT_VAL register for GPIOs > 31

commit 947c93eb29c2a581c0b0b6d5f21af3c2b7ff6d25 upstream.

The controller has two consecutive OUTPUT_VAL registers and both
holds output value for 32 GPIOs. Due to a missing adjustment, the
current code always uses the first register while setting the
output value whereas it should use the second one for GPIOs > 31.

Add the missing armada_37xx_update_reg() call to adjust the register
according to the 'offset' parameter of the function to fix the issue.
