ocf-linux: remove extension and build out of tree

	  Download it at http://download.gna.org/adeos/patches/v2.6/$(ARCH)/

	  and verify that your kernel version in buildroot matches.

	  OCF-Linux Kernel part.

	  Select this option to patch your kernel with OCF for

	  hardware-accelerated crypto support for available drivers.

	  Some libraries need to also have OCF enabled for them,

	  for example OpenSSL.

	help

	  OCF-Linux is a Linux port of the OpenBSD/FreeBSD Cryptographic

	  Framework (OCF). This port aims to bring full asynchronous HW/SW

	  crypto acceleration to the Linux kernel and applications

	  running under Linux.

	  You need to enable the OCF linux kernel extension or provide

	  a prepatched kernel to make this option useful.

	  http://ocf-linux.sourceforge.net/

Remove the OCF linux kernel extension instead opting to build ocf-linux

modules out of tree.

This is easier for users since no kernel config tweaking is required.

On the downside the OCF drivers can't be used, but then all of the

kernel crypto drivers are available to users via cryptosoft which is

preferred.
