RDMA/hns: Fix the endian problem for hns
The hip06 and hip08 run on a little endian ARM, it needs to revise the annotations to indicate that the HW uses little endian data in the various DMA buffers, and flow the necessary swaps throughout.
The imm_data use big endian mode. The cpu_to_le32/le32_to_cpu swaps are no-op for this, which makes the only substantive change the handling of imm_data which is now mandatory swapped.
This also keep match with the userspace hns driver and resolve the warning by sparse.

IB/hns: Fix the bug when free cq
If the resources of cq are freed while executing the user case, hardware can not been notified in hip06 SoC. Then hardware will hold on when it writes the cq buffer which has been released.
In order to slove this problem, RoCE driver checks the CQE counter, and ensure that the outstanding CQE have been written. Then the cq buffer can be released.

IB/hns: Fix the bug when destroy qp
If send queue is still working when qp is in reset state by modify qp in destroy qp function, hardware will hold on and don't work in hip06 SoC. In current codes, RoCE driver check hardware pointer of sending and hardware pointer of processing to ensure that hardware has processed all the dbs of this qp. But while the environment of wire becomes not good, The checking time maybe too long.
In order to solve this problem, RoCE driver created a workqueue at probe function. If there is a timeout when checking the status of qp, driver initialize work entry and push it into the workqueue, Work function will finish checking and release the related resources later.

IB/hns: Add code for refreshing CQ CI using TPTR
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.
