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.
