Ezequiel Garcia cbe1d6973d sys-kernel: enable BFQ I/O scheduler ...

BFQ is a proportional-share storage-I/O scheduler for the
blk-mq layer. Its main features are:

 * Low latency for interactive applications
 * Low latency for soft real-time applications
 * Higher speed for code-development tasks
 * High throughput
 * Strong fairness, bandwidth and delay guarantees

Note that the default blk-mq scheduler is "None", so
th BFQ scheduler must be explicitly chosen for a given
storage device.

Note also that BFQ only supports blk-mq layer, so drivers
using legacy blk layer are not affected by this change.

In particular, both HDD and SSD storage drives use
the legacy blk layer by default.
