We need global shell variables in barebox and currently try to
emulate this by sourcing scripts instead of executing them. This
adds global variable support by registering a device named 'global'
and registering device parameters on it.
This is then used to add a more flexible bootargs mechanism. Instead
of using a single variable we can now use variables beginning with
'linux.bootargs.' and 'linux.mtdparts.' which will be concatenated
together to a valid bootargs string.
This is mainly done as another step forward to a new default environment
which will make use of this.
