x86: relax RAM check in ioremap()
Kevin Winchester reported the loss of direct rendering, due to:
[ 0.588184] agpgart: Detected AGP bridge 0
[ 0.588184] agpgart: unable to get memory for graphics translation table.
[ 0.588184] agpgart: agp_backend_initialize() failed.
[ 0.588207] agpgart-amd64: probe of 0000:00:00.0 failed with error -12
and bisected it down to:
commit 266b9f8727976769e2ed2dad77ac9295f37e321e

x86: fix ioremap RAM check
this check was too strict and caused an ioremap() failure.
the problem is due to the somewhat unclean way of how the GART code
reserves a memory range for its aperture, and how it utilizes it
later on.
Allow RAM pages to be ioremap()-ed too, as long as they are reserved.
