target-openrisc: bugfix for dec_sys to decode instructions correctly
Fixed the decoding of "system" instructions (starting with 0x2) in dec_sys() in translate.c. In particular, the l.trap instruction is now correctly decoded, which enables for singlestepping and breakpoints to be set in GDB. Signed-off-by: David R. Morrison <dmorrison@invlim.com> Acked-by: Jia Liu <proljc@gmail.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
