Applied with two little changes. I enabled the board in
imx_v8_defconfig.

Also I renamed the board directory to tqma8mpxl as this aligns better
with the other TQ boards. With this we use the SoM name rather than
the baseboard name, but I think that's fine as other baseboards for this
SoM could be handled in that directory as well.
