[PATCH 7/9] drm/panel: novatek-nt36672a: Add Tianma panel for Xiaomi Mi A2

[Alexey Minnekhanov]

Add support for Tianma TL060FVXS16-00 video mode panel based on
Novatek NT36672A, used in Xiaomi Mi A2 smartphone (xiaomi-jasmine).
It shares some code with already supported panel in this driver
for xiaomi-lavender, so we can reuse the same panel deinit function.
