dpll: zl3073x: Add support for mux pin type

Add parsing for the "mux" string in the 'connection-type' pin property
mapping it to DPLL_PIN_TYPE_MUX.

Recognizing this type in the driver allows these pins to be taken as
parent pins for pin-on-pin pins coming from different modules (e.g.
network drivers).
