Subject: [PATCH 0/2] Add missing parent_map to clocks in SM6350 clock
 drivers

If a clk_rcg2 has a parent, it should also have parent_map defined,
otherwise we'll get a NULL pointer dereference when calling clk_set_rate
on those clocks.

Correct this on clocks in both gcc-sm6350 and dispcc-sm6350.
