Currently we handle the 'dumpdtb' machine sub-option ad-hoc in every board model that has an FDT. It's up to the board code to make sure it calls qemu_fdt_dumpdtb() in the right place. This means we're inconsistent and often just ignore the user's command line argument: * if the board doesn't have an FDT at all * if the board supports FDT, but there happens not to be one present (usually because of a missing -fdt option) This isn't very helpful because it gives the user no clue why their option was ignored. However, in order to support the QMP/HMP dumpdtb commands we require now that every FDT machine stores a pointer to the FDT in MachineState::fdt. This means we can handle -machine dumpdtb centrally by calling the qmp_dumpdtb() function, unifying its handling with the QMP/HMP commands. All the board code calls to qemu_fdt_dumpdtb() can then be removed. For this commit we retain the existing behaviour that if there is no FDT we silently ignore the -machine dumpdtb option.
