[PATCH v2 4/5] drm/rockchip: dw_dp: Add DisplayPort support for rk3576

[Andy Yan]

From: Andy Yan <andy.yan@xxxxxxxxxxxxxx>

The DisplayPort of the RK3576 is basically the same as that of the
RK3588, but it operates in dual-pixel mode and also support MST.

This patch only enable the SST output now.
