Remove EOL whitespace.

Add support for parameterised device tree sources to the device tree compiler.

Add a checker to dtc, based on a feature request from rwatson / brooks.
This checks that every node that has children specifies their register sizes.
This is not enabled by default, as the default sizes are sometimes required
(including by some DTS in the tree), but can help when writing new device
trees so that you can check that you actually meant the defaults.

Fix style nit in dtc man page: sentences should start on new lines.

Remove EOL whitespace.

Minor mdoc fixes.

Fix the missing sentence that ended in the middle in the man page for dtc (also
spotted by gavin).

Import new (BSDL) device tree compiler. Now built by default, so that it can't
be used on the host system (and not installed on the device, if required). The
GPL'd one is still available if there are any devices that need it (make
universe passes with it, including kernels that use fdt, but there may be some
out-of-tree ones). WITH_GPL_DTC can be used to select the old one, for now.

Probably won't be MFC'd, but we'll remove the GPL'd version in head after the
new one has had a lot more testing and ship it in 10.0.
