include: sbi_utils: Introduce an helper to get fdt base address
This simply adds an helper to get fdt address which is more explicit than sbi_scratch_thishart_arg1_ptr. Signed-off-by: Alexandre Ghiti <alexandre.ghiti@canonical.com> Reviewed-by: Xiang W <wxjstz@126.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>
