imx50-evk has duplicate memory nodes:

Fix the duplication by removing the memory node from the dtsi file
and by adding 'device_type = "memory";' in the board dts.

Current imx7d-sdb.dts has some incorrect settings about

by adding i.MX7D SDB Rev-A board support, make default
imx7d-sdb.dts for Rev-B board as usual, and introduce
imx7d-sdb-reva.dts for Rev-A board. Below are the affected

Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.

Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.

Update cooling maps to include all devices affected by individual trip
points.

This patch adds support for the emtrion GmbH emCON-MX6 modules.
They are available with imx.6 Solo, Dual-Lite, Dual and Quad
equipped with Memory from 512MB to 2GB (configured by U-Boot).

Our default developer-Kit ships with the Avari baseboard and the
EDT ETM0700G0BDH6 Display (imx6[q|dl]-emcon-avari).

The devicetree is split into the common part providing all module
components and the basic support for all SoC versions
(imx6qdl-emcon.dtsi) and parts which are i.mx6 S|DL and D|Q relevant.
Finally the support for the avari baseboard in the developer-kit
configuration is provided by the emcon-avari dts files.
