LIU Zhiwei 666e6bbf85 target/riscv: Fix itrigger when icount is used 
When I boot a ubuntu image, QEMU output a "Bad icount read" message and exit.
The reason is that when execute helper_mret or helper_sret, it will
cause a call to icount_get_raw_locked (), which needs set can_do_io flag
on cpustate.

Thus we setting this flag when execute these two instructions.
