VPP-279: Document changes for vnet/vnet/devices

Add doxygen documentation for DPDK crypto CLI command.

The move of DPDK to a plugin invalidated the local dir.dox. So moved
dpdk/dir.dox to dpdk/device/dir.dox to fix.

### nasm
Building the DPDK Crypto Libraries requires the open source project nasm (The Netwide
Assembler) to be installed. Recommended version of nasm is 2.12.02. Minimum supported
version of nasm is 2.11.06. Use the following command to determine the current nasm version:
nasm -v
CentOS 7.3 and earlier and Fedora 21 and earlier use unsupported versions
of nasm. Use the following set of commands to build a supported version:
wget http://www.nasm.us/pub/nasm/releasebuilds/2.12.02/nasm-2.12.02.tar.bz2
tar -xjvf nasm-2.12.02.tar.bz2
