rpi-update-firmware.bbclass: refactor rpi_install_firmware_to_rootfs

[liuming50]

The current rpi_install_firmware_to_rootfs has several problems:

• it's installing duplicated devicetrees to /boot/firmware, because it is installing all dtb/dtbo links but they are duplicated, for instance: uart2.dtbo and uart2-raspberrypi4-64.dtbo are pointing to a same file.
• While RPI bootfs contains all files listed in IMAGE_BOOT_FILES, a end user can customize that variable to install the files they want to be in boot partition, but rpi_install_firmware_to_rootfs does not handle it.

To fix the above, introduce a function mender_install_deployed_files which is implemented in the same way with how WIC handle IMAGE_BOOT_FILES, now the files in boot partition and the files in /boot/firmware of A/B partitions are consistent.

Hi @liuming50, care to resolve the conflict so we can merge this?

Actually, we have removed this layer from meta-mender repository and it has been moved to meta-mender-community

• 5041c90

So we need to port this patch to https://github.com/mendersoftware/meta-mender-community/

@liuming50 I am sorry that we have not warned you about this before! scarthgap update has been worked in parallel and I failed to see that your PR won't apply anymore.
