This series of patches introduces how to enable MST functionality on the qcs8300 platform. The qcs8300 platform uses dpu_8_4 hardware, which is the same as the sa8775p, but it only has one DPU. So it only has one DP0 controller, supporting 4-stream MST. This patch only enables 2-stream MST, using intf0 and intf3. The first and second patches are modifications to the correspond dt-bindings, third patch is the dp controller driver after not reuse sm8650, fourth patch is the qcs8300 dts modification which add the clk support for stream 1.
