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
