[PATCH] arch: c6x: kernel: include "linux/console.h" when 'VT' and'DUMMY_CONSOLE' enabled.

[Chen Gang]

Need include "linux/console.h" when 'VT' and 'DUMMY_CONSOLE' enabled
(e.g allmodconfig).

The related error:
  arch/c6x/kernel/setup.c: In function ‘setup_arch’:
  arch/c6x/kernel/setup.c:442:2: error: ‘conswitchp’ undeclared (first use in this function)
  arch/c6x/kernel/setup.c:442:2: note: each undeclared identifier is reported only once for each function it appears in
  arch/c6x/kernel/setup.c:442:16: error: ‘dummy_con’ undeclared (first use in this function)
