i.MX: Fix FEC code for MDIO operation selection
According to the FEC chapter of i.MX25 reference manual
When writing the MMFR register, bit 29 and 28 select the requested operation.
* 10 means read operation with valid MII mgmt frame
* 11 means read operation with non compliant MII mgmt frame
* 01 means write operation with valid MII mgmt frame
* 00 means write operation with non compliant MII mgmt frame
So while bit 28 does change beween read/write for valid MII mgmt frame, the
mening is inverted for non compliant MII mgmt frame.
Bit 29 on the other hand means read/write whatever the type of mgmt frame
involved.
So this patch change the operation selection from bit 28 to bit 29 as it is
more generic.
