platform/x86: x86-android-tablets: replace bat_swnode with swnode_group

Now that we are using software-nodes are used in more places it is
useful to have a more generic mechanism to have the core code register
software-nodes.

Replace the bat_swnode registration mechanism with a more generic
swnode_group registration mechanism.
