Statistical counters are not incrementing in some adapter versions with
newer FW. This is due to the stats context length mismatch between FW and
driver. Since the L2 driver updates the length correctly, use the stats
length from L2 driver while allocating the DMA'able memory and creating
the stats context.

This is being used to implement both the port and device global stats,
which is causing some confusion in the drivers. For instance EFA and i40iw
both seem to be misusing the device stats.
Split it into two ops so drivers that don't support one or the other can
leave the op NULL'd, making the calling code a little simpler to
understand.

- OPEN_QP doesn't involve the driver but requires a XRCD. qedr provides

- OPEN/CLOSE_XRCD are the ops alloc_xrcd()/dealloc_xrcd()
- CREATE_SRQ/DESTROY_SRQ are the ops create_srq()/destroy_srq()
- QUERY/MODIFY_SRQ is op query_srq()/modify_srq(). hns sets this but

- RESIZE_CQ is op resize_cq(). bnxt_re sets this boes doesn't supply an op
- ALLOC/DEALLOC_MW is alloc_mw()/dealloc_mw(). cxgb4 provided an

All drivers were checked that no drivers provide the op without also

The code in setup_dma_device has become rather convoluted, move all of
this to the drivers. Drives now pass in a DMA capable struct device which
will be used to setup DMA, or drivers must fully configure the ibdev for
DMA and pass in NULL.
Other than setting the masks in rvt all drivers were doing this already
anyhow.
mthca, mlx4 and mlx5 were already setting up maximum DMA segment size for
DMA based on their hardweare limits in:
__mthca_init_one()
dma_set_max_seg_size (1G)
__mlx4_init_one()
dma_set_max_seg_size (1G)
mlx5_pci_init()
set_dma_caps()

Other non software drivers (except usnic) were extended to UINT_MAX [1, 2]
instead of 2G as was before.
