Conversion to resource-managed iomap was buggy causing init failures
on both vt6420 and 6421 - BAR5 wasn't mapped for both controllers
while on vt6420 sata_via tried to map BAR0-4 twice. Fix it.

I thought I have a vt6421 but mine too was a vt6420. So, the patch is
verified only for vt6420 but, the vt6421 path is pretty obvious and
should be correct. Please apply.
