net: phy: bugfixes: mv88E61xx multichip addressing support
With these fixes, this driver works properly for multi chip
addressging mode
Bugfixes:
1. Build error fixed for function mv88e61xx_busychk_multic-fixed
2. PHY dev address error detection- fixed
3. wrong busy bit was refered in function mv88e61xx_busychk -fixed
4. invalid data read ptr was refered for RD_PHY in case of
multichip addressing mode -fixed
The Multichip Address mode is tested with RD6281A board having
MV88E6165 switch on it
