net/mlx4_en: Doorbell is byteswapped in Little Endian archs
[ Upstream commit 492f5add4be84652bbe13da8a250d60c6856a5c5 ]
iowrite32() will byteswap it's argument on big endian archs.
iowrite32be() will byteswap on little endian archs.
Since we don't want to do this unnecessary byteswap on the fast path,
doorbell is stored in the NIC's native endianness. Using the right
iowrite() according to the arch endianness.
