f5128432b0 crypto: jitterentropy - remove unnecessary information from a comment 
The clocksource does not provide clocksource_register() function since
f893598 commit (clocksource: Mostly kill clocksource_register()), so
let's remove unnecessary information about this function from a comment.

0c5f0aa5dd crypto: jitterentropy - use safe format string parameters 
Since the API for jent_panic() does not include format string parameters,
adjust the call to panic() to use a literal string to avoid any future
callers from leaking format strings into the panic message.

dfc9fa9193 crypto: jitterentropy - avoid compiler warnings 
The core of the Jitter RNG is intended to be compiled with -O0. To
ensure that the Jitter RNG can be compiled on all architectures,
separate out the RNG core into a stand-alone C file that can be compiled
with -O0 which does not depend on any kernel include file.

As no kernel includes can be used in the C file implementing the core
RNG, any dependencies on kernel code must be extracted.

A second file provides the link to the kernel and the kernel crypto API
that can be compiled with the regular compile options of the kernel.
