Add support for 3 panels used in 2 Xiaomi smartphones, all based on Qualcomm SDM636/660 SoC:
* Shenchao panel used in Xiaomi Redmi Note 7 (xiaomi-lavender), the exact model string is unknown * Tianma TL063FVMCA01-00 for Xiaomi Redmi Note 7 (xiaomi-lavender) * Tianma TL063FVMC43-02 for Xiaomi Redmi Note 6 Pro (xiaomi-tulip) They all are DSI video mode panels using Novatek NT36672A controller, so they can share almost exactly the same init/off sequences with minimal differences between variants. This allows to avoid a lot of code duplication.
