[PATCH 03/10] devinfo: make the output of "devinfo DEVICE" nicer

* some output sections started with "foo: bar", some with "foo = bar". Unify this.
* there was a fixed size to the "foo =" parameters, which wasn't fitting, this
  was especially visible at "devinfo global"
* don't output "resources:", "driver:" and "bus:" lines if there are none
  resources, drivers or busses involved.
* remove some empty lines
* harmonize differentiation between headlines (e.g. "resources:") and values
  by indenting values slightly
* uppercase some texts
