arch/arm/src/lpc17xx_40xx/lpc17_40_ethernet.c: Follow the procedure listed in the LPC176x/5x User Manual when reading from and writing to the PHY's registers (section 10.11.14). I couldn't see any behavioral change after this commit, but nonetheless is a good practice to follow the manufacturer's recommended procedure.
