[PATCH 10/11] globalvar: Add support for printing all global variables

[Sascha Hauer]

This could previously only be done with 'devinfo global'. While
this is still possible this adds a more direct access via the
globalvar command. This variant also adds a '*' in front of
the variable if the corresponding non volatile variable exists.
