Just sent a v2, which hopefully will fix this problem for all i.MX dtsi files.

Removal of skeleton.dtsi from imx6qdl.dtsi caused a regression on SolidRun platforms as the /chosen and /memory nodes are no longer populated. Fix this by adding the nodes into the platform .dtsi files. Uncompressing Linux... done, booting the kernel.
