[PATCH v2 2/2] drm/msm/dsi: Add phy configuration for QCM2290

[Dmitry Baryshkov]

From: Loic Poulain <loic.poulain at linaro.org>

The QCM2290 SoC a the 14nm (V2.0) single DSI phy. The platform is not
fully compatible with the standard 14nm PHY, so it requires a separate
compatible and config entry.
