video: console: add missing MODULE_DESCRIPTION() macros

With ARCH=i386, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/video/console/mdacon.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes three other files which, although they did not produce a
warning with the i386 allmodconfig configuration, may cause this
warning with other configurations.
