lan743x: Use correct MAC_CR configuration for 1 GBit speed
Corrected the MAC_CR configuration bits for 1 GBit operation. The data
sheet allows MAC_CR(2:1) to be 10 and also 11 for 1 GBit/s speed, but
only 10 works correctly.
Devices tested:
Microchip Lan7431, fixed-phy mode
Microchip Lan7430, normal phy mode
Fixes: 6f197fb63850 ("lan743x: Added fixed link and RGMII support")
