The DPI driver currently relies on the timings in omap_dss_device struct to
configure the DISPC accordingly. This makes the DPI interface driver dependent
on the omap_dss_device struct.
Make the DPI driver data maintain it's own timings field. The panel driver is
expected to call dpi_set_timings()(renamed to omapdss_dpi_set_timings) to set
these timings before the panel is enabled.
In the set_timings() op, we still ensure that the omap_dss_device timings
(dssdev->panel.timings) are configured. This will later be configured only by
the DPI panel drivers.

omap_panel_config contains fields which are finally written to DISPC_POL_FREQo
registers. These are now held by omap_video_timings and are set when the manager
timings are applied.
Remove the omap_panel_config enum, and remove all it's references from panel or
interface drivers.

Some panel timing related fields are contained in omap_panel_config in the form
of flags. The fields are:
- Hsync logic level
- Vsync logic level
- Data driven on rising/falling edge of pixel clock
- Output enable/Data enable logic level
- HSYNC/VSYNC driven on rising/falling edge of pixel clock
Out of these parameters, Hsync and Vsync logic levels are a part of the timings
in the Xorg modeline configuration. So it makes sense to move the to
omap_video_timings. The rest aren't a part of modeline, but it still makes
sense to move these since they are related to panel timings.
These fields stored in omap_panel_config in dssdev are configured for LCD
panels, and the corresponding LCD managers in the DISPC_POL_FREQo registers.
Add the above fields in omap_video_timings. Represent their state via new enums.
Add these parameters to the omap_video_timings instances in the panel drivers.
Keep the corresponding IVS, IHS, IPC, IEO, RF and ONOFF flags in
omap_panel_config for now. The struct will be removed later.

Remove configuration of Ac-bias pins
Ac-bias pins need to be configured only for passive matrix displays. Remove
acbi and acb fields in omap_dss_device and their configuration in panel
drivers. Don't program these fields in DISP_POL_FREQo register any more.
The panel driver for sharp-ls037v7dw01, and the panel config for
Innolux AT070TN8 in generic dpi panel driver set acb to a non zero value. This
is most likely carried over from the old omapfb driver which supported passive
matrix displays.

Remove OMAP_DSS_LCD_TFT as a omap_panel_config flag.
We don't support passive matrix displays any more. Remove this flag from all the
panel drivers.
Force the display_type to OMAP_DSS_LCD_DISPLAY_TFT in the interface drivers.

Fix two problems in PicoDLP driver's error handling on
picodlp_panel_power_on:
- If omapdss_dpi_display_enable() failed, the its error value was not
returned
- If picodlp_i2c_init() failed, dssdev->state was erroneously set to
OMAP_DSS_DISPLAY_ACTIVE

PicoDLP is a micro projector from TI.
DLP used in OMAP4 is dpp2600 (DLP Pico Projector) The DLP requires
commands to be sent over i2c for configurations. To know more about
dpp2600 commands please visit:
https://focus.ti.com/myti/docs/extranet.tsp?sectionId=403
The picodlp module consists of a dss driver and an i2c_client.
