[PATCH v2 4/7] newport_con: Implement struct consw.con_unblank

[Thomas Zimmermann <tzimmermann@suse.de>]

Implement con_unblank from struct consw with the VESA_NO_BLANKING
branch from newport_blank(). Remove that code from the blank helper.

Both helpers, newport_blank() and newport_unbank(), clear or set
a single flag in a hardware register. No further VESA DPMS blanking
is supported.
