revert nvvar changes

[Sascha Hauer]

It was a bad idea to not sync nvvars to corresponding globalvars.
Doing so caused several regressions of which at least one is still
standing. Currently expanding linux bootargs with nv.linux.bootargs.*
doesn't work since the code looks for global.linux.bootargs.* which
no longer exist.

Let's revert all this stuff and forget about it. Sorry for the
inconvenience.
