include: fdt/fdt_helper: Change fdt_get_address() to return root.next_arg1
In sbi_domain_finalize(), when locating the coldboot hart's domain,
the coldboot hart's scratch->arg1 will be overwritten by the domain
configuration. However scratch->arg1 holds the FDT address of the
coldboot hart, and is still being accessed by fdt_get_address() in
later boot process. scratch->arg1 could then contain completely
garbage and lead to a crash.
To fix this, we change fdt_get_address() to return root domain's
next_arg1 as the FDT pointer.
Resolves: https://github.com/riscv-software-src/opensbi/issues/281
Fixes: b1678af210dc ("lib: sbi: Add initial domain support")
