Public bug reported:

[ Impact ]

U-Boot variable $fdtfile should have the vendor name as prefix (e.g.
allwinner/sun20i-d1-nezha.dtb) to match the directory structure in the
ESP where we place the initial device-tree.

This allows to use first boot without devicetree command in grub.cfg

[ Test Plan ]

Install the updated u-boot-nezha on the preinstalled images for
Allwinner Nezha D1 and LicheeRV Dock.

Check that $fdtfile matches the Linux device-tree paths.

Check that the images can be booted.

[ Where problems could occur ]

Loading the correct device-tree might fail if the value of $fdtfile does
not match the vendor directory and file name in Linux.

Booting might fail.

[ Other Info ]

Allwinner Nezha D1 and LicheeRV Dock are the only boards supported by
u-boot-nezha. As the boards are not supporting the RVA23 ISA, Ubuntu
24.04 LTS is the newest supported release.
