Description

Mainline kernel 6.3 and above implements yt8531 driver. This pull request removes the legacy driver patch and fix the device tree for Orange Pi 4 LTS and other devices to use that driver.

Note: this PR has a "dependency" upon this other PR (https://github.com/armbian/build/pull/5290) - these two PRs are unrelated, but the PR-5290 bug does not allow me to easily test without having conflicts later. This is just a note, everything should go on flawlessy once PR-5290 is merged.

Jira reference number AR-1774
