[PATCH] nios2: add screen_info

[PATCH] nios2: add screen_info

[Sudip Mukherjee]

The build of nios2 was failing with the error:
drivers/built-in.o: In function `vgacon_switch':
vgacon.c:(.text+0x12174): undefined reference to `screen_info'
vgacon.c:(.text+0x1217c): undefined reference to `screen_info'
drivers/built-in.o: In function `vgacon_resize':
vgacon.c:(.text+0x123f4): undefined reference to `screen_info'
vgacon.c:(.text+0x123f8): undefined reference to `screen_info'
drivers/built-in.o: In function `vgacon_save_screen':
vgacon.c:(.text+0x12528): undefined reference to `screen_info'

Lets define a screen_info which can work as the vga console.
