{linux,device,u-boot}-pine64-pinenote: move to community from testing

Per https://docs.postmarketos.org/pmaports/main/device-categorization.html

• Maintained by at least one person (me :) )
• Well documented installation instructions on device wiki page (see https://wiki.postmarketos.org/wiki/PINE64_PineNote_(pine64-pinenote))
• Close-to-mainline kernel (kernel 6.17.8, based on upstream sources, patched with close-to-mainline diff)
• Kernel must pass pmbootstrap kconfig check --community, which includes working firewall (#1119 (closed)) (this option doesn't seem to exist anymore)
• Automatic kernel upgrades must worK (kernel is in /boot, so yes)
• Maintainer(s) must take part in the workflow for new postmarketOS releases (with pleasure!)
• Join the testing channel coordinate the release (done)
• Kernel must be upgraded regularly; (I follow patch releases within a (couple) week, see !7364 (merged))

Following changes need to be made (in seperate MR)

• U-boot using EFI rather the extlinux (!7462 (merged))
• Move kernel to LLVM, and integrate kconfig changes for community (!7461 (merged))
• Drop phosh and sway-systemd subpackage (!7470 (merged))
• Consolidate subpackages to corner off opinionated configs (!7515 (merged))
• Upgrade kernel to 6.18 (!7518 (merged))
• [X] Remove pinenote-dbus-service in favor of pinenote-service (optional) (!7547 (closed))
