History
Nate Lawson d22e9c6e0d Correctly handle BIOS resources that are duplicated (!). There are many 
systems that have overlapping regions specified in their sysresource
objects.  This patch fixes ATA DMA and acpi_timer allocation for such
sysctems.  It should eventually be moved to resource_list_add() if it is
a valid generalized approach.  The minimal approach for 5.3 is:

"Loop through all current resources to see if the new one overlaps
any existing ones.  If so, the old one always takes precedence and
the new one is adjusted (or rejected).  We check for three cases:

1. Tail of new resource overlaps head of old resource:  truncate the
   new resource so it is contiguous with the start of the old.
2. New resource wholly contained within the old resource:  error.
3. Head of new resource overlaps tail of old resource:  truncate the
   new resource so it is contiguous, following the old."
