For some reason we don't have dtb subdirectories.
Tested locally to pass pmbootstrap install and checked /boot for dtbs
[ci:skip-build]: already built successfully in CI
This device port uses U-Boot as a basic bootloader. Users should install
U-Boot and reinstall pmOS to the U-Boot version of port (this one).
Thus an upgrade from old installations that depend on old vendor bootloader
is not implemented.
Instruction how to install U-Boot can be found on dedicated page of
pmOS wiki.
