This patch replaces the ib_device_attr.max_sge with max_send_sge and
max_recv_sge. It allows ulps to take advantage of devices that have very
different send and recv sge depths. For example cxgb4 has a max_recv_sge
of 4, yet a max_send_sge of 16. Splitting out these attributes allows
much more efficient use of the SQ for cxgb4 with ulps that use the RDMA_RW
API. Consider a large RDMA WRITE that has 16 scattergather entries.
With max_sge of 4, the ulp would send 4 WRITE WRs, but with max_sge of
16, it can be done with 1 WRITE WR.

Change the drivers to call ib_query_port in their get port
immutable handler instead of their own query port handler.
Doing this required to set the core cap flags of this device
before the ib_query_port call is made, since the IB core might
need these caps to serve the port query.
Drivers are ensured by the IB core that the port attributes passed
to the port query verb implementation are zero, and hence we
removed the zeroing from the drivers.

This patch added the code for refreshing CQ CI using TPTR in hip06
SoC.
We will send a doorbell to hardware for refreshing CQ CI when user
succeed to poll a cqe. But it will be failed if the doorbell has
been blocked. So hardware will read a special buffer called TPTR
to get the lastest CI value when the cq is almost full.
This patch support the special CI buffer as follows:
a) Alloc the memory for TPTR in the hns_roce_tptr_init function and
free it in hns_roce_tptr_free function, these two functions will
be called in probe function and in the remove function.
b) Add the code for computing offset(every cq need 2 bytes) and
write the dma addr to every cq context to notice hardware in the
function named hns_roce_v1_write_cqc.
c) Add code for mapping TPTR buffer to user space in function named
hns_roce_mmap. The mapping distinguish TPTR and UAR of user mode
by vm_pgoff(0: UAR, 1: TPTR, others:invaild) in hip06.
d) Alloc the code for refreshing CQ CI using TPTR in the function
named hns_roce_v1_poll_cq.
e) Add some variable definitions to the related structure.

This lock will be used in query port interface, and will be called
while IB device was registered to OFED framework/IB Core. So, the
lock of iboe must be initiated before IB device was registered.

The parameter named collapsed unused in hns_roce_cq_alloc.
Also, parameter named doorbell_lock unsed in
hns_roce_v1_cq_set_ci. This patch optimize these parameters.

In the latest IB core version, it has some known issues
with memory registration using the local_dma_lkey.
Thus RoCE don't expose support for it, and remove
device->local_dma_lkey which is introduced to working systems.
