ARM: dts: imx6qdl: add TQMa6{S,Q,QP} SoM

Add device trees for TQMa6S, TQMa6Q, and TQMa6QP embedded modules.
The A and B SoM variants are for hardware revisions that differ in
how the I2C devices are connected. For details, see [1].

This is a combination of the patches
"arm: dt: imx6qdl: add tqma6[qdl] som on mba6 mainboard",
"arm: dt: tqma6: add spi with spi nor flash on SOM",
"arm: dt: add basic support for tqma6qp on mba6", and
"arm: dt: imx6qdl-tqma6: use generic jedec,spi-nor"
from the TQMa6x BSP, with the MBa6 specific parts removed.
