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.

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.

The goal is to have debug code always compiled during build.
We standardize all debug output on the following format:
[QOM_TYPE_NAME]reporting_function: debug message
The qemu_log_mask() output is following the same format as the
above debug.

* A generic PHY was added (borrowwed from LAN9118)
* The buffer management is also modified as buffers are
slightly different between Coldfire and i.MX
