This patch series adds support to phylink and sfp pluggable module.
Add software-nodes to hold the network interface phylink, sfp, i2c and gpio
configuration and integrates the PCI1x1x chip i2c driver and gpio driver to
access the sfp module eeprom data.

Tested on chip PCI11010 Rev-B with Bridgeport Evaluation board Rev-1 with
following SFP modules:

1. FS's 2.5G SFP (SFP-2.5G-T) with 2.5 Gbps speed (interface 2500Base-X)

2. Mellanox DAC10G SFP (MC3309130-001) at 2.5 Gbps speed (interface 2500Base-X)
and 1Gpbs speed (interface 1000Base-X)

3. Axcen's 1G SFP (AXGT-R1T4-05I1) at 1G/100M/10M bps speed (interface SGMII)

4. Fiber 1G SFP (AXGE-1354-0531) at 1Gpbs speed (interface 1000Base-X)

Change Log:
===========
V0 -> V1:
  - Integrate with Synopsys DesignWare XPCS drivers
  - Based on external review comments,
    - Changes made to SGMII interface support only 1G/100M/10M bps speed
    - Changes made to 2500Base-X interface support only 2.5Gbps speed
    - Add check for not is_sgmii_en with is_sfp_support_en support
    - Change the "pci11x1x_strap_get_status" function return type from void to  
      int
    - Add ethtool phylink wol, eee, pause get/set functions
