Extending uverbs_ioctl header with driver_id and another reserved field. driver_id should be used in order to identify the driver. Since every driver could have its own parsing tree, this is necessary for strace support. Downstream patches take off the EXPERIMENTAL flag from the ioctl() IB support and thus we add some reserved fields for future usage.

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.

We move all the eq process code for hip06 from hns_roce_eq.c into hns_roce_hw_v1.c, and also for hns_roce_eq.h. With these changes, it will be convenient to add the eq support for later hardware version.

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 doesn't add any new functionality.
