IB/uverbs: Add alloc/free dm uverbs ioctl support
This change adds uverbs support for allocation/freeing of device memory commands. A new uverbs object is defined of type idr to represent and track the new resource type allocation per context. The API requires provider driver to implement 2 new ib_device callbacks - one for allocation and one for deallocation which return and accept (respectively) the ib_dm object which represents the allocated memory on the device. The support is added via the ioctl command infrastructure only.
