unmaintained/alcatel-idol347-downstream: new device (Alcatel Idol 3 4.7)

Based on @Minecrell work at: https://gitlab.com/Minecrell/pmaports/-/tree/alcatel-idol347-downstream adapted smb1360 shared patches for idol347 downstream tree, and added his idol347-like-mainline.patch gist which changes downstream DT to mimic sane mainline settings for easy battery driver dump comparison.
