The unpriv APIs can be useful to external firmware and out-of-tree platform support code. This patch adds "sbi_" prefix to unpriv load/store APIs and rename struct riscv_unpriv to struct sbi_trap_info everywhere. We also place struct sbi_trap_info in sbi/sbi_trap.h so that we can use it for sbi_trap_redirect() as well. Overall, this patch will make naming of unpriv APIs consistent with other OpenSBI APIs.
