The STB pin controller represents a family whose silicon instances
are found e.g. on BCM2712 SoC.

In particular, on RaspberryPi 5, there are two separate instantiations
of the same IP block which differ in the number of pins that are
associated and the pinmux functions for each of those pins. The
-aon- variant stands for 'Always On'.

Depending on the revision of the BCM2712 (CO or D0), the pin
controller instance has slight differences in the register layout.

Fixed up the extraneous label and whitespace error
and applied this patch!
