This makes it work better on modern LS/LX platforms and avoids
unnecessary delays. Also fixes a lock leak.

We've removed kernel option EXT_RESOURCES almost two years ago.
While it was ok to have some code under a common 'extres' subdirectory

so no need to have it under a cryptic name.

No need to keep it under sys/arm64/rockchip
It's easier to find which controller we support by looking under one directory.
While here remove the condition on SOC option, device rk_i2c is enough as all
Rockchip SoC that we support have this controller.
