drm/ast: Rework I/O register setup
There are three different ways of retrieving the I/O-memory ranges
for AST devices: either from PCI BAR 1, from PCI BAR 2 or from PCI
BAR 1 by 'guessing'.
Make the respective code more readable by making each case self-
contained. Also add error checking against the length of the PCI
BARs.
v2:
* fix I/O range length to 128 bytes
* fix length test for PCI BAR 2
