This patch remove a superfluous DCD command in TX53-xx30 flash header.
The entry DCD_WR_CMD(0x21c) just duplicates the contents of the last
imx_flash_header_v2 struct member dcd.
Removal of this DCD entry is needed to make the TX53 board boot again
from NAND.

We support two different board revisions, both of which only differ
in the dcd table, so we can support both in a single binary with the
cost of storing both dcd tables in the binary.

This redefines the sdram controller registers as offsets to the base
rather than as absolute addresses. All users are fixed to use the
SoC specific base address.

board_init_lowlevel is no longer called from generic code, so we can't
just return from in. Instead we have to jump to board_init_lowlevel_return
manually. For the a9m2440 board one case was missed to convert. This
is broken since:

| ARM: give boards control of the reset entry point
|
| On some SoCs (for example AM35xx), the ROM bootloader passes useful
| information in r0 when jumping to barebox.
|
| To avoid overwriting this in the generic reset code, we introduce
| common_reset as a C function and as an assembler macro. This is then
| called form the reset entry point (either in common or in board code).
|
| This patch is based on code by Sascha Hauer <s.hauer@pengutronix.de>.

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.

On i.MX we enable all necessary clocks during startup of the clock
controller driver, so we do not need the register hacking in the drivers
anymore.

All i.MX SoCs now use the same imx_silicon_revision() function to get
the revision. Add a separate header file for it and a common function
used on all SoCs.

This adds the device id mechanism to the i.MX fec driver and
uses it to determine the fec version. Also adds devicetree
probing support.

Since we have phylib the phy won't be detected after poweron. It seems
the phy needs some time after reset.
