simple-panel is not a valid panel model, so there is no data (video
timings, etc.) associated with it. Therefore drivers can't do anything
useful with it, so it should not appear in the table of OF matches.

Device trees will always need to specify the exact model of the panel.

The bits-per-color is provided by the EDID normally, but if we're using
panels, we need to store it somewhere. So we add a field to the panel
descriptor for it.

In order to differentiate between the different video modes (burst vs.
non-burst, sync pulses vs. sync events) supported by peripherals, pass
the flags that specify this mode in the panel description to the DSI
peripheral device when probed.

The enable GPIO for panels may be provided by GPIO expanders on slow
busses (such as I2C), and therefore toggling the GPIO may sleep. Since
these accesses don't happen in interrupt context, use the *_cansleep()
variants of the GPIO API.

Add a driver for simple panels. Such panels can have a regulator that
provides the supply voltage and a separate GPIO to enable the panel.
Optionally the panels can have a backlight associated with them so it
can be enabled or disabled according to the panel's power management
mode.

Support is added for two panels: An AU Optronics 10.1" WSVGA and a
Chunghwa Picture Tubes 10.1" WXGA panel.
