This commit introduces 8-bit, 16-bit, 32bit, 64bit I/O device memory read/write operations along with the relaxed versions. The weakly-ordered machine like ARM needs additional I/O barrier for device memory read/write access over PCI bus. By introducing the eal abstraction for I/O device memory read/write access, The drivers can access I/O device memory in architecture agnostic manner. The relaxed version does not have additional I/O memory barrier, useful in accessing the device registers of integrated controllers which implicitly strongly ordered with respect to memory access.
