Just duplicated the functions to take the needed
arguments from the private MR context. The old
fast_reg routines will be dropped later.

If the device support arbitrary sg list mapping (device cap
IB_DEVICE_MAP_ARB_SG set) we allocate the memory regions with
IB_MR_MAP_ARB_SG and skip the counce buffer work around.

If ib_alloc_mr is called with IB_MR_MAP_ARB_SG, the driver
allocate a private klm list instead of a private page list.
And set the UMR wqe correctly when posting the fast registration.
Also, expose device cap IB_DEVICE_MAP_ARB_SG
