Clément Léger	9c78593269	lib: sbi: add Ssdbltrp ISA extension support ... Add Ssdbltrp trap handler support for S-mode double trap handling. If the trap is received while in VS-mode, then the trap is redirected to S-mode. If caught while in HS-mode, then an error is returned to the top trap handler which will panic.
