Linux booting protocol mandates that register "a0" contains the hartid. However, U-Boot can not pass the hartid via a0 during standard UEFI protocol. DT nodes are commonly used to pass such information to the OS. Add a DT node under chosen node to indicate the boot hartid. EFI stub in Linux kernel will parse this node and pass it to the real kernel in "a0" before jumping to it.
