Just format the code without modifying anything, including fixing some
redundant and missing blanks and spaces and changing the variable
definition order.

Current names of functions are not proper, such as hns_roce_free_cq,
actually it means free cqc, thus we rename them. Furthermore, functions
used inside one file can be named without the prefix hns_roce_ which will
make the functions for verbs symbols more eye-catching.

BT is used to retrieve the addresses of the contexts(QPC/MPT/CQC/SRQC)
in memory. In order to support multi hop addressing for the contexts,
the BT BA should be configured by mailbox, and the BT attribution will
be set by command.
This patch is to configure the BT BA and BT attribution for the
contexts.

If the resources of mr are freed while executing the user case, hardware
can not been notified in hip06 SoC. Then hardware will hold on when it
reads the payload by the PA which has been released.
In order to slove this problem, RoCE driver creates 8 reserved loopback
QPs to ensure zero wqe when free mr. When the mac address is reset, in
order to avoid loopback failure, we need to release the reserved loopback
QPs and recreate them.
