Add support for Visionox panel driver.
Signed-off-by: Harigovindan P <harigovi@codeaurora.org>
---
Changes in v2:
- Dropping redundant space in Kconfig(Sam Ravnborg).
- Changing structure for include files(Sam Ravnborg).
- Removing backlight related code and functions(Sam Ravnborg).
- Removing repeated printing of error message(Sam Ravnborg).
- Adding drm_connector as an argument for get_modes function.
Changes in v3:
- Adding arguments for drm_panel_init to support against mainline.
Changes in v4:
- Removing error messages from regulator_set_load.
- Removing dev struct entry.
- Removing checks.
- Dropping empty comment lines.
Changes in v5:
- Removing unused struct member variables.
- Removing blank lines.
- Fixed indentation.
- Invoking dsi_detach and panel_remove while early exiting from probe.
Changes in v6:
- Changed "35597" to "rm69299" for power_on function.
- Removing rm69299_config since it supports single type of panel for now.
- Fixed alignment.
- Using goto statements when regulator_set_load fails.

the common way to do this kind of unwinding in the kernel would be to add
something like this before 'err_dsi_attach':
err_set_load:
mipi_dsi_detach(dsi);
and then just do 'goto err_set_load' in the error paths.
