drivers: hid: Trackpad off by default for Blake

This change makes the trackpad disabled by default for Blake. If this is
done from userspace, there is a race condition where you can still move
the trackpad for a bit before the trackpad disable code kicks in.

So instead of enabled by default and override to disabled, do the
opposite. Disable in kernel by default and then the userspace can choose
to enable it when needed.
