video: restore CONFIG_VIDCONSOLE_AS_LCD as boolean
This patch restores CONFIG_VIDCONSOLE_AS_LCD as boolean
and introduce a separate sting as CONFIG_VIDCONSOLE_AS_NAME
to search this string in stdout used as videoconsole.
This patch avoid issue with board defconfig or code expecting
CONFIG_VIDCONSOLE_AS_LCD as boolean.

+ This is a work-around for boards which have 'lcd' or 'vga' in their
+ stdout environment variable, but have moved to use driver model for
+ video. In this case the console will no-longer work. While it is
+ possible to update the environment, the breakage may be confusing for
+ users. This option will be removed around the end of 2020.
