Remove the unused argument (i.e. struct ethtool_regs *regs) in
lan743x_common_regs( ) function arguments.

It seems that you do more here than what you said.
You remove the unused argument but you also remove the memset. And it
is a problem because p is not initialized anymore.

Add support to SGMII register dump

Signed-off-by: Raju Lakkaraju <Raju.Lakkaraju@microchip.com>
---
Change List:
============
V5 -> V6:
 - Split change in two patches (i.e. unused argument in lan743x_common_regs
   change and SGMII register dump)
 - Fix the "ARRAY_SIZE" issue

V4 -> V5:
 - Remove the debug read function macro
 - Add auto variable structure to handle register definitions

V3 -> V4:
 - No changes. Patch on tags 6.1-rc1

V2 -> V3:
 - Remove the private flag option.
   As per review comment, use -w/-W to configure dump flag.
   But, change to -w/-W option, EEPROM/OTP data might be corrupt
   in case of wrong flag input.
   Need to fix this properly in future development.

V1 -> V2:
 - Add set_dump and get_dump_flag functions

V0 -> V1:
 - Removed unwanted code
