board-inspector: use the same _MIN and _MAX for 0-length regions 

It is typical in AML resource descriptors to have 0-length region
descriptors which are typically templates of resources that are not
assigned on the current platform. For such regions, the `base + length - 1`
formula does not calculate the max of the region properly.

This patch updates the resource descriptor parsers to use max = min when
the length of the region is 0.
