It's been five years since we introduced the v2 uAPI and
the major consumer libgpiod is at v2.2.3.

Let's discourage the old ABI.

Changes in v2:
- Rebase on v7.0-rc1
- Do not explicitly state "default n", n is the default.
- Drop RFC, I waited like two years+
- Link to v1: https://lore.kernel.org/r/20231104-no-y-uapi1-default-v1-1-f60d318b6fbe@linaro.org

Buildroot is still at libgpiod v1.6.5.

Applied, thanks!

[1/1] Do not enable the v1 uAPI by default
