Many of the DSI flags have names opposite to their actual effects,
e.g. MIPI_DSI_MODE_EOT_PACKET means that EoT packets will actually
be disabled. Fix this by including _NO_ in the flag names, e.g.
MIPI_DSI_MODE_NO_EOT_PACKET.

I considered adding _DISABLE_ instead, but that'd make the
flag names a big too long.

Generated with:
flag=MIPI_DSI_MODE_VIDEO_HFP; git grep $flag | cut -f1 -d':' | \
  xargs -I{} sed -i -e "s/$flag/MIPI_DSI_MODE_VIDEO_NO_HFP/" {}
flag=MIPI_DSI_MODE_VIDEO_HBP; git grep $flag | cut -f1 -d':' | \
  xargs -I{} sed -i -e "s/$flag/MIPI_DSI_MODE_VIDEO_NO_HBP/" {}
flag=MIPI_DSI_MODE_VIDEO_HSA; git grep $flag | cut -f1 -d':' | \
  xargs -I{} sed -i -e "s/$flag/MIPI_DSI_MODE_VIDEO_NO_HSA/" {}
flag=MIPI_DSI_MODE_EOT_PACKET; git grep $flag | cut -f1 -d':' | \
  xargs -I{} sed -i -e "s/$flag/MIPI_DSI_MODE_NO_EOT_PACKET/" {}
(then minor format changes)

Changes in v3:
 - Added all R-b tags from v1 and v2 (hopefully didn't miss any).

Changes in v2:
 - Rebased on latest linux-next, after some of the flags got fixed
   (Linus Walleij).
