Support GPIO pins above 31

[sarfata]

Right now we only support writing to the first GPIO register when setting or clearing pins. I do not think setting a GPIO above 32 works. But if we just changed our code a little bit, we could support it.

In the datasheet, page 90, we can see that there are two GPIO registers. One for GPIO from 0 to 31 and one for GPIO 32 to 53.

We should support using this if the channel number is > 32.
