[PATCH v2 0/5] Add framebuffer on Xiaomi Poco F1 and disable the MDSS on tianma panel variant

Enable framebuffer for early console output.

Due to broken panel driver on tianma and no visual output it's better
to disable the MDSS so the framebuffer stays on.

In case second patch gets rejected, please apply the first one standalone
