During the GPL to GPL/X11 licensing migration, the GPL notice introduced
mentionned the device trees as a library, which is not really accurate. It
began to spread by copy and paste. Fix all these library mentions to reflect
the file that it's actually just a file.

The dma controller requires that the ahb1 bus clock be driven by pll6
for peripheral access to work. Previously this was done in the dma
controller driver, but was since removed as part of a series to unify
the ahb1_mux and ahb1 clock drivers, in

    14e0e283 dmaengine: sun6i: Remove obsolete clk muxing code

Unfortunately the rest of that series did not make it, leaving us with
broken dma on sun6i.

This patch reparents ahb1_mux to pll6 using the DT assigned-clocks
properties in the dma controller node.

The current GPL only licensing on the DTSI makes it very impractical for other
software components licensed under another license.

In order to make it easier for them to reuse our device trees, relicense our
DTSI first under a GPL/X11 dual-license. Hopefully, the DTS will follow soon.
