[PATCH 1/2] video: lcd: Remove useless BACKLIGHT_LCD_SUPPORT kernel symbol

From: Alexander Shiyan <hidden>
Date: 2018-12-16 05:02:58 

Symbol BACKLIGHT_LCD_SUPPORT affecting anything, except enabling
the backlight & LCD Kconfig menu. The patch removes this symbol as
useless and converts it into a menu.

Something bothered me about the patch but I think its the lack of
explanation in the patch header about *why* we don't use/need/want
BACKLIGHT_LCD_SUPPORT.

Essentially the reason BACKLIGHT_LCD_SUPPORT is useless is that we have
two _CLASS_DEVICE configs (LCD_CLASS_DEVICE and BACKLIGHT_LCD_DEVICE)
that do the same job (ad that do have code attached to them).

It would be good to mention that in the patch header.
