The Modem Subsystem clock provider have a bunch of generic properties

we don't seem to be referencing the
mss_mfab_axi and mss_nav_axi in the
mss clk driver though, do we really
need them in bindings? If we dont
can we drop the clock-names as well.
They are linked as parent for the clocks. So we need them.
