Subject: [PATCH 0/4] Add MST support for qcs8300 platform

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.
