realtek: Use MII_BMCR and BMCR_* constants from <linux/mii.h>

Browse Source 
Replace numerical values, BIT(x) and (1 << x) in
drivers/net/phy/rtl83xx-phy.c with constants from <linux/mii.h> to
improve code readability.

To make reviewing easier, this commit only addresses MII_BMCR and BMCR_*
constants.
