csky: kprobe: Fixup code in simulate without 'long'
The type of 'val' is 'unsigned long' in simulate_blz32, so 'val < 0'
can't be true.
Cast 'val' to 'long' here to determine branch token or not,

csky: Add kprobes supported
This patch enable kprobes, kretprobes, ftrace interface. It utilized
software breakpoint and single step debug exceptions, instructions
simulation on csky.
We use USR_BKPT replace origin instruction, and the kprobe handler
prepares an excutable memory slot for out-of-line execution with a
copy of the original instruction being probed. Most of instructions
could be executed by single-step, but some instructions need origin
pc value to execute and we need software simulate these instructions.
