i.MX: Fix FEC code for MDIO address selection
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.
