boards: Add phytec-som-imx6 ...

The main idea behind this patch is to avoid redundant code.  Because of
the module similarities of all i.MX6 based phytec boards, we can merge
its code.

The phytec-som-imx6 merges the code of all i.MX6 based phytec SOMs.  So
we will have only one "board" in the barebox for phyCARD-i.MX6 and
phyFLEX-i.MX6.

ARM: i.MX6: add Technexion Wandboard support ...

This adds support support for the i.MX6 Technexion Wandboard. The

The baord type is autodetected based on the SoC type, so all boards
can be supported by the same binary image.

This enabled multi image support for the Garz&Fricke Vincell board. Also

Previously we used the same image on both the Vincell and the Vincell-LT

this was good for quite some confusion internally, so let's properly
introduce a second image.

i.MX: Add provisions to boot from IRAM ...

This commit add a very basic code to allow Barebox to be booted from
IRAM. Given that the amount of IRAM on most i.MX variants is
insufficient to contain a copy of Barebox with any reasonable degree
of functionality this code uses IRAM only as a temporary location and
eventually bootstraps from DRAM. But the presense of the intermediate
IRAM-only stage allows to add provisions to test the area of DRAM that
Barebox would be using to facilitate various testing scenarious.

This patch adds high assurance boot support (HABv4) image generation to
barebox, currently tested on i.MX6 only.

Here the default i.MX6 CSF file $(havb4_imx6csf) is used, it's generated during
build on from the template "scripts/habv4/habv4-imx6.csf.in". You can configure
the paths to the SRK table and certificates via: System Type -> i.MX specific
settings -> HABv4 support.

The proprietary tool "cst" by Freescale tool is expected in the PATH.

Use COMMON_CLK_OF_PROVIDER to provide clocks from the device tree.
This needs several changes:
- use the clock number defines from dt-bindings/clock/imx6qdl-clock.h
- register the (previously skipped) gates, because these are bound to
  the consumers
- select COMMON_CLK_OF_PROVIDER

With this we also no longer register the fixed clocks twice.

The parameters ECC Strength, BadBlockMarkerByte and BadBlockMarkerStartBit in

use them in the bbu handler.

Revert "ARM: i.MX: Make NAND related Kconfig options depend on MTD" ...

This reverts commit 4b17d73c7da2, as it is incomplete and partially
broken. ARCH_IMX_EXTERNAL_BOOT_NAND does not depend on MTD, it just uses
some defines from the mtd/nand header, but does not actually depend on MTD
being compiled in.

For the other two cases there is a more complete fix merged with commit
57b584d748d4 that also enables the needed MTD write support.

Fixes:
(MACH_TX25 && MACH_PCA100 && MACH_PCM038) selects ARCH_IMX_EXTERNAL_BOOT_NAND
which has unmet direct dependencies (ARCH_IMX && MTD)
