c6x: kernel: setup: Include "linux/console.h" if both VT and DUMMY_CONSOLE enabled

This patch below is sent from my other email address ([email protected]), but is rejected by [email protected], so I forward it by my original email address.

Excuse me, I will leave current company soon (sunrus.com.cn), so I have to change my email address too. At present, gmail in China is still not stable enough, so I have to use other personal email: [email protected].

If linux-kernel mailing list can not accept personal qq email address, please let me know, I shall try to look for another personal email addresses.

Thanks.
