[PATCH v3 5/7] sticon: Implement struct consw.con_unblank

[Thomas Zimmermann]

Implement con_unblank from struct consw. The new function is called
sticon_unblank(). Remove the related code from sticon_blank().

There is no display unblanking in sticon: only return true to redraw
the console.

v3:
- take mode_switch from parameter
