Andrew Jones ccfe866220 RISC-V: Align SBI probe implementation with spec 
commit 41cad8284d5e6bf1d49d3c10a6b52ee1ae866a20 upstream.

sbi_probe_extension() is specified with "Returns 0 if the given SBI
extension ID (EID) is not available, or 1 if it is available unless
defined as any other non-zero value by the implementation."
Additionally, sbiret.value is a long. Fix the implementation to
ensure any nonzero long value is considered a success, rather
than only positive int values.

Fixes: b9dcd9e415 ("RISC-V: Add basic support for SBI v0.2")
