jtag: tcl: change drscan usage to show at least one value is required 

It's customary to use [] brackets to mean the argument is optional, but
drscan requires at least one pair of "num_bits value" so change it to ().
In common regular expressions * means 0 or more, and + means 1 or more,
so change that too.
