platform: msm_shared: Add vbif qos remapper support in LK

Each MDP source pipe can generate 4 levels of priority and
those priorities are remapped before reaching the AXI bus.
These re-mapper settings depends on the chip-set and the
nature of the control path source pipe is used in. Provide
support to implement this configuration.
