This patch tidies up the code. I have run Linden (and verified with checkpatch)
many part of the driver trying to reorganize some sections respecting the
codying-style rules in the points where it was not done.

This patch is to support the extend descriptors available
in the chips newer than the 3.50.
In case of the extend descriptors cannot be supported,
at runtime, the driver will continue to work using the old style.
In detail, this support extends the main descriptor structure
adding new descriptors: 4, 5, 6, 7. The desc4 gives us extra
information about the received ethernet payload when it is
carrying PTP packets or TCP/UDP/ICMP over IP packets.
The descriptors 6 and 7 are used for saving HW L/H timestamps (PTP).
V2: this new version removes the Koption added in the first implementation
because all the checks now to verify if the extended descriptors are
actually supported happen at probe time.

In mixed burst (MB) mode, the AHB master always initiates
the bursts with fixed-size when the DMA requests transfers
of size less than or equal to 16 beats.
This patch adds the MB support and the flag that can be
passed from the platform to select it.
MB mode can also give some benefits in terms of performances
on some platforms.
v2: fixed Coding Style

This patch re-works the internal GMAC DMA parameters
passed from the platform.
In the past, we only passed the pbl but, with new core,
other parameters can be passed and are mandatory on some
platforms.
New parameters are documented in stmmac.txt because this
patch has an impact for many platforms.

This patch uses an mdelay to manage the timeout on
sw reset to be independant of cpu_clk.

Move the STMicroelectronics driver into driver/net/ethernet/stmicro/ and
make the necessary Kconfig and Makefile changes.
