[PATCH v2 7/8] build: make most device classes optional

[Bruce Richardson <bruce.richardson@intel.com>]

Apart from ethdev and cryptodev, which have lots of components and tests
which depend on them, we can make the device class libraries optional
without too much work.

This patch marks:
* bbdev,
* compressdev,
* dmadev,
* eventdev,
* mldev,
* rawdev,
* regexdev
optional, and ensures that DPDK - including tests - can be built with
these components disabled.
