The existing device tree is too big for the 64K byte constrained first stage. Because of the size limitation it might be better to only use the device tree for the second stage. This increases user-friendliness by leaving space for PBL_CONSOLE.
For now provide a slightly smaller smaller *-boot-bin.dts device tree for first stage, which can be further stripped in future commits.
