Extending ili9881c driver support for nwe080 panel

drm/panel: ilitek-ili9881c: Clean up on mipi_dsi_attach failure

mipi_dsi_attach is allowed to fail, and currently the probe
code doesn't clean up (mainly drm_panel_remove) if this happens.

Add cleanup code on failure.

drm/panel: panel-ilitek9881c: Add prepare_upstream_first flag

The panel sends MIPI DCS commands during prepare and is expecting
the bus to remain in LP-11 state in-between.

Set the prepare_upstream_first flag so that the upstream DSI host
is prepared / pre_enabled first, and therefore the bus is in a
defined state.

drm/panel: panel-ilitek9881c: Use cansleep methods

Use cansleep version of gpiod_set_value so external IO drivers (like
via I2C) can be used.

drm/panel: panel-ilitek9881c: Crystalfontz support

Add support for Crystalfontz CFAF7201280A0-050Tx panel.

drm/panel: ilitek-ili9881c: Allow configuration of the number of lanes

Not all panels use all 4 data lanes, so allow configuration based
on the compatible string.

drm/panel: ili9881: Add configuration for the new panels

Add configuration for the 5" and 7" Raspberry Pi 720x1280
DSI panels based on ili9881.

drm: panel: ili9881: Correct symmetry on enable/disable return codes

ili9881c_enable is always returning 0.

ili9881c_disable was returning the error code from
mipi_dsi_dcs_set_display_off.
If non-zero, the drm_panel framework will leave the panel marked as
enabled, and not run the enable hook next time around. That isn't
helpful, particularly as we're expecting unprepare to disable
resets and regulators.

Change ili9881c_disable to match enable in always returning 0.

drm: panel: ili9881: Add option to reconfigure setup commands

The driver is typically asking for LP commands, but then tries
to send set_display_[on|off] from enable/disable when the host
will be in HS mode.
It also sends shutdown commands just before it asserts reset and
disables the regulator, which is rather redundant.

Add an option to configure these two choices from the panel_desc.

Update panel-ilitek-ili9881c.c

Correcting display dimension typo

ILI9881C: Update timings for CFAF7201280A0-050TX

Update of ILI9881C CFAF7201280A0-050TX panel timing to work with the CM5.

drm/panel: ilitek-ili9881c: Restore lanes configuration for nwe080 panel

This config was missing with the forward porting of the rasp pi kernel to
6.12. Refer to https://github.com/raspberrypi/linux/issues/6856
