Add micro-USB connector under "muic" node to properly represent the hardware. Deprecate also the old "max77693-muic" in favor of generic "muic" (this is max77693, so there is no need to state it in its child nodes). This "muic" node is used only to instantiate MUIC driver by compatible, thus actual Linux driver changes are needed. Extend the example with this new code.
