OMAPDSS: Taal: remove external backlight support
Taal panel driver supports two kinds of backlight control: 1) using DSI commands sent to the panel to control the backlight, 2) calling function pointers going to the board file to control the backlight. The second option is a bit hacky, and will no longer be needed when the PWM driver supports the backlight features. After that we can use the standard PWM backlight driver. This patch removes the second backlight control mechanism, and adds a boolean field, use_dsi_backlight, to nokia_dsi_panel_data which the board file can use to inform whether the panel driver should use DSI commands to control the backlight.
