The driver uses a static int once variable to alloc the
rx packets. remove this to make the driver multi instance
safe. While at it, remove the crappy selfmade alignment.
dma_alloc_coherent returns sufficiently aligned memory.

We never supported the sigmatel stm chips and probably
never will. So do the first step and rename the architecture
to mxs just like in the kernel.

The i.MX28 comes with an extended ethernet controller (ENET/FEC) which
is backwards compatible to the FEC known from other i.MX CPUs. Add a few
adaptions to the existing driver to make it work with the MX28 FEC.

Some register bits are not defined in the IMX CPUs using this FEC (at least
I did not find anything about them in the related datasheets) and they will
get (partially) a new meaning in the i.MX28 CPU. So, removing them from the
source seems the best way to avoid any accidental usage on i.MX28.

if fec was allocated using malloc. if fec->miiphy->dev->driver != 0

edev was allocated using malloc. On one board (NOR boot), we met data abort
in eth_register (at dev_add_param(dev, &edev->param_ip);).
Allocating edev with xzalloc (as in several other drivers) fixed the problem.

We need to redo buffer initialization each time we open
the device, not only once on init time. Otherwise network
does not work if the last transfer was interrupted with
ctrl-c

This driver is not only used on i.MX27 but on i.MX35 and i.MX25, so
rename it to a more generic name
