[PATCH 3/4] x86: ioremap: remove physical address warning message

[Kenji Kaneshige]

Current ioremap() code for x86 displays warning message if too high
address to handle is passed. But this can happen as usual cases. For
example, if 64-bit BAR is assigned to a PCI device and its device
driver calls pci_iomap(). So this patch changes the warning messages
as follows.

- Change printk message from KERN_WARNING to KERN_DEBUG
- Remove WARN_ON_ONCE()
