The TX6 boards come with 3 different PMIC variants from which we
currently only support the ltc3673. Detect the other two by i2c
address and set them up correctly. The code is based on the karo
U-Boot port.

The i.MX6q variant is basically the same as the i.MX6dl variant, just
with another SoC and the usual i.MX6q/i.MX6dl adjustments.

The TX6 board come with either NAND flash or eMMC as primary
storage medium. This adds support for the eMMC variants.
We can detect if we have NAND or eMMC by looking at the
bootsource which will be configured accordingly. This
way we can modify the device tree during runtime and do
not have to create a new image.

The Karo TX6X family consists of different i.MX6Q/DL based System-on-Modules.
Add support for the TX6u 801x modules, that have an i.MX6DL SoC.
