According to the FEC chapter of i.MX25 reference manual When writing to MMFR register, the MDIO device and adress are selected by bit 27 to 23 and bit 22 to 18 respectively. This is a total of 10 bits that need to be used by the Phy chip/address decoding function. This patch fixes the number of bits used from 9 to 10.
