69f9cb16de net: imx: limit buffer descriptor count
i.MX Fast Ethernet Controller uses buffer descriptors to manage
data flow to/fro receive & transmit queues. While transmitting
packets, it could continue to read buffer descriptors if a buffer
descriptor has length of zero and has crafted values in bd.flags.
Set an upper limit to number of buffer descriptors.

b72d8d257c i.MX: Standardize i.MX FEC debug
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.

fcbd8018e6 i.MX: Add FEC Ethernet Emulator
This is based on mcf_fec.c FEC implementation for Coldfire

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