[ Upstream commit 5f8d3ab136d0ccb59c4d628d8f85e0d8f2761d07 ]
With the introduction of commit 3edfb7bd76bd ("gpiolib: Show correct
direction from the beginning") the gpiolib will attempt to read the
direction of all pins, which triggers a read from protected register
regions.
The pins 0 through 3 and 81 through 84 are protected, so mark these as
reserved.
