x86: soften multi-BAR mapping sanity check warning message
Impact: make debug warning less scary
The ioremap() time multi-BAR map warning has been causing false
positives:
http://lkml.org/lkml/2008/12/10/432
http://lkml.org/lkml/2008/12/11/136
So make it less scary by making it once-per-boot, by making it KERN_INFO
and by adding this text:
"Info: mapping multiple BARs. Your kernel is fine."
