Use the correct display pins (which are DISP2* and not DISP1*) and
use the of_graph bindings to describe the video hardware.

This enabled multi image support for the Garz&Fricke Vincell board. Also
it adds the Vincell-LT as a second image with a separate device tree.
Previously we used the same image on both the Vincell and the Vincell-LT
image since the differences are not that significant for barebox. Still
this was good for quite some confusion internally, so let's properly
introduce a second image.

Instead of putting hardware specific bit masks in platform_data just
use the decimal interface width and encode this in the driver. This
makes it easier to create the platform_data and helps device tree
based implementations.

Above the 0x800 offset the manufacturer provides the board type, a serial

In order to enable and use USB/OHCI on the MPC5200 the USB PLL register must be
set.
It's not easy to find a correct value for this register, it seems it depends on
the used external reference frequency and some other 'magic' things. There are
some values out in the wild for the 33,333333 MHz and 33,333000 MHz reference
frequency case, but they are not consistent over the boards.
The value used here in this change for the USB PLL register is from the first
days of support for this platform and works at least on the reference
baseboard.

Patch is based on Linux upstream patch:
commit e2c5eb78a3cc9b0d69ae924c33da50a4cd6d1fa4
Author: Tony Lindgren <tony@atomide.com>
The GPMC binding is obviously very confusing as the values
are all over the place. People seem to confuse the GPMC partition
size for the chip select, and the device IO size within the GPMC
partition easily.
The ranges entry contains the GPMC partition size. And the
reg entry contains the size of the IO registers of the
device connected to the GPMC.
Let's fix the issue according to the following table:
Device GPMC partition size Device IO size
connected in the ranges entry in the reg entry
NAND 0x01000000 (16MB) 4
16550 0x01000000 (16MB) 8
smc91x 0x01000000 (16MB) 0xf
smc911x 0x01000000 (16MB) 0xff
OneNAND 0x01000000 (16MB) 0x20000 (128KB)
16MB NOR 0x01000000 (16MB) 0x01000000 (16MB)
32MB NOR 0x02000000 (32MB) 0x02000000 (32MB)
64MB NOR 0x04000000 (64MB) 0x04000000 (64MB)
128MB NOR 0x08000000 (128MB) 0x08000000 (128MB)
256MB NOR 0x10000000 (256MB) 0x10000000 (256MB)
Let's also add comments to the fixed entries while at it.

The files flash-header-*.imxfg contains two defines which are use in
include files flash-header-phytec-*.h. The first define is SETUP_MDCFG0.
In the second define name some RAM size value were used, e.g.
SETUP_S_DL_512MB_1GB or SETUP_1GIB_2GIB_4GIB.
It's better to name also the second define after the register names,
here MMDC1_MDCTL and MMDC1_MDASP, because these values changes for every
RAM configurations and it's consistent with the first define.

The current calculation does not take the 0x10000000 offset where
SDRAM starts into account. For example with a 1GiB chip density
the current code calculates cs1 start to 0x40000000, but it
has to be 0x10000000 + 0x40000000 = 0x50000000. Add the missing
8 32MiB chunks.
