Subject: 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.
