drivers/video/concole: add negative dependency for VGA_CONSOLE on ARC
Architectures which support VGA console must define screen_info structurture from "uapi/linux/screen_info.h". Otherwise undefined symbol error occurs. Usually it's defined in "setup.c" for each architecture. If an architecture does not support VGA console (ARC's case) there are 2 ways: define a dummy instance of screen_info or add a negative dependency for VGA_CONSOLE in to prevent selecting this option. I've implemented the second way. However the best solution is to add HAVE_VGA_CONSOLE option for targets which support VGA console. Then turn off VGA_CONSOLE by default and add dependency to HAVE_VGA_CONSOLE. But right now it's better to just add a negative dependency for ARC and then consider how to collaborate about this issue with maintainers of other architectures.
