dong.yang 3e141a6950 firmware: fw_base.S: fix multi-core boot bug.
In a multi-core startup scenario, if both _try_lottery and
_wait_for_boot_hart use the data in the _boot_status address, when
a CPU enters OpenSBI later than boot hart set the _boot_status to
BOOT_STATUS_BOOT_HART_DONE, the CPU will modify _boot_status to 1
by amoswap.w and will never be awakened in _wait_for_boot_hart.
So let _try_lottery and _boot_status use data from two addresses.
