Samuel Holland afa0e3091b lib: sbi_trap: Add support for vectored interrupts ...

When redirecting an exception to S-mode, transform the (v)stvec CSR
value as described in the privileged spec to derive the S-mode PC.
Since OpenSBI never redirects interrupts, only synchronous exceptions,
the only action needed is to mask out the (v)stvec.MODE field.
