docs: admin-guide: add a series of orphaned documents

There are lots of documents that belong to the admin-guide but
are on random places (most under Documentation root dir).

Move them to the admin guide.

-Linux support for random number generator in i8xx chipsets
-==========================================================
-
-Introduction
-============
-
-The hw_random framework is software that makes use of a
-special hardware feature on your CPU or motherboard,
-a Random Number Generator (RNG).  The software has two parts:
-a core providing the /dev/hwrng character device and its
-sysfs support, plus a hardware-specific driver that plugs
-into that core.
-
-To make the most effective use of these mechanisms, you
-should download the support software as well.  Download the
-latest version of the "rng-tools" package from the
-hw_random driver's official Web site:
-
-	http://sourceforge.net/projects/gkernel/
-
-Those tools use /dev/hwrng to fill the kernel entropy pool,
-which is used internally and exported by the /dev/urandom and
-/dev/random special files.
-
-Theory of operation
-===================
-
-CHARACTER DEVICE.  Using the standard open()
-and read() system calls, you can read random data from
-the hardware RNG device.  This data is NOT CHECKED by any
-fitness tests, and could potentially be bogus (if the
-hardware is faulty or has been tampered with).  Data is only
-output if the hardware "has-data" flag is set, but nevertheless
-a security-conscious person would run fitness tests on the
-data before assuming it is truly random.
-
-The rng-tools package uses such tests in "rngd", and lets you
-run them by hand with a "rngtest" utility.
-
-/dev/hwrng is char device major 10, minor 183.
-
-CLASS DEVICE.  There is a /sys/class/misc/hw_random node with
-two unique attributes, "rng_available" and "rng_current".  The
-"rng_available" attribute lists the hardware-specific drivers
-available, while "rng_current" lists the one which is currently
-connected to /dev/hwrng.  If your system has more than one
-RNG available, you may change the one used by writing a name from
-the list in "rng_available" into "rng_current".

-About the Intel RNG hardware, from the firmware hub datasheet
-=============================================================
-
-The Firmware Hub integrates a Random Number Generator (RNG)
-using thermal noise generated from inherently random quantum
-mechanical properties of silicon. When not generating new random
-bits the RNG circuitry will enter a low power state. Intel will
-provide a binary software driver to give third party software
-access to our RNG for use as a security feature. At this time,
-the RNG is only to be used with a system in an OS-present state.

-Intel RNG Driver notes
-======================
-
-FIXME: support poll(2)
-
-.. note::
-
-	request_mem_region was removed, for three reasons:
-
-	1) Only one RNG is supported by this driver;
-	2) The location used by the RNG is a fixed location in
-	   MMIO-addressable memory;
-	3) users with properly working BIOS e820 handling will always
-	   have the region in which the RNG is located reserved, so
-	   request_mem_region calls always fail for proper setups.
-	   However, for people who use mem=XX, BIOS e820 information is
-	   **not** in /proc/iomem, and request_mem_region(RNG_ADDR) can
-	   succeed.
