[dpdk-dev] [PATCH] i40e: Fix the endian issue for the i40e read&write registers functions

[Zhe Tao <zhe.tao@intel.com>]

Linux kernel uses the writel and readl related functions to perform the PCI memory access via ioremap region,
those functions will handle the big little endian properly by doing the conversion between little and big endian if necessary,
so Add this conversion in the read&write registers functions for i40e.
