arm/dt: Allow CONFIG_OF on ARM
Add some basic empty infrastructure for DT support on ARM.
v5: - Fix off-by-one error in size calculation of initrd
- Stop mucking with cmd_line, and load command line from dt into
boot_command_line instead which matches the behaviour of ATAGS booting
v3: - moved cmd_line export and initrd setup to this patch to make the
series bisectable.
- switched to alloc_bootmem_align() for allocation when
unflattening the device tree. memblock_alloc() was not the
right interface.
