[PATCH] blspec: drop explicit devicetree "none" handling

[Ahmad Fatoum]

The bootloader spec mentions only that the devicetree key is optional
and doesn't list none as special value. THe barebox behavior on none
is completely bonkers as it attempts to delete barebox' own device
tree, which nowadays fails with an error message.

Drop that special handling altogether.
