ARM: 6271/1: Introduce *_relaxed() I/O accessors
This patch introduces readl*_relaxed()/write*_relaxed() as the main I/O
accessors (when __mem_pci is defined). The standard read*()/write*()
macros are now based on the relaxed accessors.
This patch is in preparation for a subsequent patch which adds barriers
to the I/O accessors.
