[PATCH 09/10] defaultenv: don't use global.linux.bootargs.dyn.* in boot entries

[Sascha Hauer <s.hauer@pengutronix.de>]

Boot entries no longer need to put their Kernel command line options
into global.linux.bootargs.dyn.*, as boot_entry() reverts all changes to
global.linux.bootargs.* when the boot entry returns. Use plain names in
the net and dfu boot entries, the boot entry template and the matching
example in the documentation.

Unlike the dyn.ip and dyn.root variables, which bootscript_boot()
creates for compatibility with existing boot scripts, the new variables
don't exist beforehand, so create them with the global command.

 ``boot net`` will then retrieve the kernel (and also the device tree and
 initramfs, if used) over TFTP and boot it.
