[PATCH v3] bridge: Elaborate a bit on dumb VGA bridges in Kconfig

[Linus Walleij]

It's better if we explain a bit that this pertains to
non-programmable VGA DAC bridges.

ChangeLog v2->v3:
- Fix wording and commit message.
- Collect Laurent's review tag.
ChangeLog v1->v2:
- Write that these bridges are non-programmable rather than
  discrete, as that reflects the name of the bridge being
  "dumb". Discrete is wrong as it has a specific electronic
  meaning, as in "non-integrated" and this is integrated.
