This patch only moves files to their new locations, before applying the
next two patches adding the NTB Abstraction layer. Splitting this patch
from the next is intended make distinct which code is changed only due
to moving the files, versus which are substantial code changes in adding
the NTB Abstraction layer.

ntb: use errata flag set via DID to implement workaround2014-10-17T11:08:51+00:00Dave Jiangdave.jiang@intel.com2014-08-28T20:53:18+00:00urn:sha1:069684e888da73f175da0f10fe26da4f450d8c18
Instead of using a module parameter, we should detect the errata via
PCI DID and then set an appropriate flag. This will be used for additional
errata later on.

Many variable names in the NTB driver refer to the primary or secondary
side. However, these variables will be used to access the reverse case
when in NTB-RP mode. Make these names more generic in anticipation of
NTB-RP support.

NTB: Use DMA Engine to Transmit and Receive2013-09-05T18:04:09+00:00Jon Masonjon.mason@intel.com2013-02-12T16:52:50+00:00urn:sha1:282a2feeb9bfb1d1dfbad93df206b74eaf80d564
Allocate and use a DMA engine channel to transmit and receive data over
NTB. If none is allocated, fall back to using the CPU to transfer data.
