- Document that padlock(4) pretends to accelerate HMAC algorithms.

- Remove "device cryptodev" as it is not needed for compiling padlock(4)
  into the kernel. Actually it is not advisable, because padlock
  instructions can be used directly from userland, so passing the work
  through the kernel is a bad idea.
