Vybrid GPIOs

Something that keeps confusing me.  Difference between:
- PTA0, PTB1, ... naming scheme
- GPIO_0 - GPIO_134 naming scheme
- the 5 gpu controllers

Toradex colibri som manual:

The mapping between the port name (e.g. PORT0[27]) and pad name
(e.g. PTB5) of the GPIO can be found in the same table in section 4.4.

PAD_83 PORT2[19] PTD4
