Revert "doc: posix: mark posix device io as complete"

This reverts commit d9855da.

PR zephyrproject-rtos#73978 introduced a regression.
Unfortunately this PR cannot be reverted without reverting also
Let's revert both PRs to stabilize main again towards the 3.7 release.

For more details on the issue see
zephyrproject-rtos#75205
