Let's start trying to get a handle on it by splitting out the eDP panels. This patch does this: 1. Start by copying simple-panel verbatim over to a new driver, simple-panel-edp. 2. Rename "panel_simple" to "panel_edp" in the new driver. 3. Keep only panels marked with `DRM_MODE_CONNECTOR_eDP` in the new driver. Remove those panels from the old driver. 4. Remove all recent "DP AUX bus" stuff from the old driver. The DP AUX bus is only possible on DP panels. 5. Remove all DSI / MIPI related functions from the new driver. 6. Remove bus_format / bus_flags from eDP driver. These things don't seem to make any sense for eDP panels so let's stop filling in made up stuff. In the end we end up with a bunch of duplicated code for now. Future patches will try to address _some_ of this duplicated code though some of it will be unavoidable. NOTE: This may not actually move all eDP panels over to the new driver since not all panels were properly marked with `DRM_MODE_CONNECTOR_eDP`. A future patch will attempt to move wayward panels I could identify but even so there may be some missed.

This panel is found in the Samsung GT-I8160 mobile phone, and possibly some other mobile phones. This display needs manufacturer commands to configure it; the commands used in this driver were taken from downstream driver by Gareth Phillips; sadly, there is almost no documentation on what they actually do. This driver re-uses the DBI infrastructure to communicate with the display. This driver is heavily based on WideChips WS2401 display controller driver by Linus Walleij and on other panel drivers for reference.

This panel is _almost_ able to be controlled in a "simple" way (and it originally was implemented in panel-simple.c), but it's really impossible to get the backlight semantics right there without adding wacky special-case code to panel-simple. Let's give up and clone the parts of panel-simple that we need and implement the power sequence that this panel needs. NOTE: we'll still leave the devicetree bindings alone. Even though the power-sequencing is non-standard the bindings are still "simple".
