sunxi: video: Force h/vsync active high when using ext. vga dac on some boards

On both my A13-OLinuxIno and my A13-OLinuxIno-Micro, the vga output gives an
unstable image when active low v or hsync is used.

The problem seems to be specific to the OLinuxIno A13 (normal & micro)
boards. I've just looked up the schematics and they use an opendrain driver
for the vga sync lines, and with sync pulses it is the logical high->low
edge of the pulse which counts for the timing, which with an active low
sync is being driven by the pull-up, and that simply seems to not drive
it hard enough to get a stable image.

So force v and hsync active high on these boards. independent of what the
modeline says. This fixes the unstable image.

with what patman/git send-email really do.  Some basic examples:
- If an email address is addressed via "Series-cc" and "Patch-cc" patman
  shows that email address would be CC-ed two times.
- If an email address is addressed via "Series-to" and "Patch-cc" patman
  shows that email address would be sent TO and CC-ed.
- If an email address is addressed from a combination of tag aliases,
  get_maintainer.pl output, "Series-cc", "Patch-cc", etc patman shows
  that the email address would be CC-ed multiple times.

Patman currently does try to send duplicate emails like the --dry-run
output shows, but "git send-email" intelligently removes duplicate
addresses so this patch shouldn't change the non-dry-run functionality.

Change patman's output and email addressing to line up with the
"git send-email" logic.  This trims down patman's dry-run output and
prevents confusion about what patman will do when emails are actually
