dsi_panel: Add support the state of the touch screen

Browse source 
Touch have a feature named "single tap".
    1. When the feature enbled, we can not power down panel,
        and keep rest signal high.
    2. When the feature disabled, the touch state is  0, Instead,
        the touch state is 1.
    3. Touch driver will call set() function to set the touch state,
        And panel driver will call check() function to check  state.
