baytrail: remove gfx read_resources() work around

Before the special PUNIT settings the GFX pci device
had the same device id as the transaction router. This
required a special case in the transaction router's
driver to do the proper thing for read_resources().
However, that requirement is no longer needed as the
PUNIT special message is now being done. Therefore,
remove the work around.

BUG=None
BRANCH=None
TEST=Built and looked at resource allocation logs to confirm
     work around is no longer needed.
