I am aware that in the Linux Kernel vendor subdirectories are used for
arm64 dtbs.

I was questioning about U-Boot. I could not find any usage of
subdirectories for other arm64 boards:

hikey_defconfig: fdtfile=hi6220-hikey.dtb
dragonboard410c_defconfig: fdtfile=apq8016-sbc.dtb

but

odroid-c2_defconfig: fdtfile=amlogic/meson-gxbb-odroidc2.dtb
