arm64/dt: add machine name to kernel call stack dump output
This installs the machine name as recorded by setup_machine_fdt()
as dump stack arch description. This results in the string to be
included in call stack dumps, as is shown here:
...
Bad mode in Synchronous Abort handler detected, code 0x84000005
CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.18.0-rc2+ #548
> Hardware name: linux,dummy-virt (DT)
task: ffffffc07c870000 ti: ffffffc07c878000 task.ti: ffffffc07c878000
PC is at 0x0
...
Note that systems that support DMI/SMBIOS may override this later.
