Revert "x86: cap iomem_resource to addressable physical memory"
This reverts commit 95ee14e4379c5e19c0897c872350570402014742.
Mikael Petterson <mikepe@it.uu.se> reported that at least one of his
systems will not boot as a result. We have ruled out the detection
algorithm malfunctioning, so it is not a matter of producing the
incorrect bitmasks; rather, something in the application of them
fails.
Revert the commit until we can root cause and correct this problem.
-stable team: this means the underlying commit should be rejected.
