cmd: add rdcycle test to RISC-V exception command
Some versions of KVM don't allow access to the cycle CSR.
Provide a command 'exception rdcycle' for testing.
If the cycle CSR is accessible, we get an output like:
=> exception rdcycle
cycle = 0x41f7563de
If the cycle CSR is not accessible, we get an output like:
=> exception rdcycle
Unhandled exception: Illegal instruction
Put subcommands into alphabetical order in long help.
