lib: Better naming of unpriv APIs for wider use
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.
