[Ubuntu 15.10] CAPI flash driver

[bugproxy]

This is a new driver for accessing CAPI attach flash. This will use the new in kernel CAPI API in bz 124336. This provides access to the flash using a new "superpipe" mechanism (ie. direct user space access to flash) and also via a legacy kernel block driver.

having problem to have the code accepted upstream (even for 4.3), so, it might get deferred. Still having internal discussions.
