Within the allowable range of the DSI spec, this time needs to be reduced to avoid panel exceptions. Base on the branch of linus/master v6.3. Change since v3: 1. Rebase. Change since v2: 1. Remove the applied patch. 2. Change the commit title and the description. Change since v1: 1. Added fine-tuning panel power sequence modification.
