Let's move it to the same place as well in barebox.

Setting up the MIPI unit is necessary for proper IPU support,
so set this up here. This is only needed for graphics in barebox,

The esdctl devices are currently not in the devicetrees. this means
they are not registered when booting from the devicetree. Move the
device registration from soc_devices_init to soc_init which is called
even with devicetree support so that we get esdctl devices.

Each i.MX SoC has its own SoC initcall. To ease multi SoC support
move it to a single initcall.

The same value as used in Mainline and Freescale U-Boot. This might
increase the stability of i.MX51 boards. The 5:1 ratio we have in barebox
probably goes back to copy/paste from the i.MX53 code.

imx_silicon_revision() can't be used from early init context, so
use imx51_silicon_revision() instead.

The IROM is located at physical address 0x0, so reading the
silicon revision from it leads to a NULL pointer dereference
if done too late when the MMU is already enabled. Use the IIM
instead which is also done in the Kernel. This limits the silicon
revisions to 2.0 and 3.0, but I assume the earlier versions are
not seen in the wild anyway.

This also moves the call to imx_set_silicon_revision() out of
imx51_silicon_revision() so that imx51_silicon_revision() can be called
in early init context.

This is a port of the official PLL errata workaround from Freescale.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.

This is based on U-Boot commit:

The value for i.MX53 216MHz is actually 432MHz. Use the same value
as for i.MX51 which really corresponds to 216MHz. These are the same
PLL216 values as U-Boot uses.

Rename the barebox_loc environment variable to bootsource, since
- barebox_loc is a mixture between abbriviation and fulltext which is not nice
- technically it describes the source the SoC has booted from. This is not
  necessarily barebox but could also be some other first stage loader.

Rather than doing this in the SoC specific code just print
it in imx_set_silicon_revision. This saves some lines of code
and also results in i.MX27 now also having the silicon revision
printed during startup.

This moves the known i.MX bootsource settings to a single file
so that the code can be shared. Also we add a enum for the different
boot sources so that it can be used in C Code and not only on the shell.
The pcm038 board is changed to use it instead of digging in the registers
manually.
