[PATCH net-next V2 0/5] Add support to SFP for PCI11x1x chips

[Raju Lakkaraju <Raju.Lakkaraju@microchip.com>]

This is the follow-up patch series of
https://lkml.iu.edu/hypermail/linux/kernel/2310.2/02078.html

Divide the PHYLINK adaptation and SFP modifications into two separate patch
series.

This patch series focuses on sfp support for PCI11x1x chips.

Tested on PCI11010 Rev-1 Evaluation board with following SFP modules:
 1. FS's 2.5G SFP (SFP-2.5G-T) with 2.5 Gbps speed (interface 2500Base-X)
 2. Axcen's 1G SFP (AXGT-R1T4-05I1) at 1G/100M/10M bps speed (interface SGMII) 

Change Log:
===========
V1 -> V2:
  - Split the patches to "PHYLINK" and "SFP" parts
  - Change variable name from "chip_rev" to "fpga_rev"
  - SFP GPIO definitions and other macros move from lan743x_main.c to
    lan743x_main.h file
  - Change from "PCI11X1X_" to "PCI11X1X_EVB_PCI11010_" strings for GPIO macros
  - Add platform_device_unregister( ) when sfp register fail
  - Add two new patches to this patch series
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
