RDMA/erdma: Unify the names related to doorbell records
...
There exist two different names for the doorbell records: db_info and
db_record. We use dbrec for cpu address of the doorbell record and
dbrec_dma for dma address of the doorbell recordi uniformly.

RDMA/erdma: Refactor the storage structure of MTT entries
...
Currently our MTT only support inline mtt entries (0 level MTT) and
indirect MTT entries (1 level mtt), which will limit the maximum length
of MRs. In order to implement a multi-level MTT, we refactor the
structure of MTT first.

RDMA/erdma: Inline mtt entries into WQE if supported
...
The max inline mtt count supported is ERDMA_MAX_INLINE_MTT_ENTRIES.
When mr->mem.mtt_nents == ERDMA_MAX_INLINE_MTT_ENTRIES, inline mtt
is also supported, fix it.

RDMA/erdma: Notify the latest PI to FW for reflushing when necessary
...
Firmware is responsible for flushing WRs in HW, and it's a little
difficult for firmware to get the latest PI of QPs, especially for RQs
after QP state being changed to ERROR. So we introduce a new CMDQ command,
by which driver can notify to latest PI to FW, and then FW can flush all
posted WRs.

RDMA/erdma: Implement atomic operations support
...
Add atomic operations support in post_send and poll_cq implementation.
Also, rename 'laddr' and 'lkey' in struct erdma_sge to 'addr' and 'key',
because this structure is used for both local and remote SGEs.

RDMA/erdma: Extend access right field of FRMR and REG MR to support atomic
...
To support atomic operations, IB_ACCESS_REMOTE_ATOMIC right should be
passed to hardware for permission check. Since "access mode" field in FRMR
SQE and RegMr command is never used by hw, we remove the "access mode"
field, so that we can then have enough space to extend access fields.

RDMA/erdma: Remove redundant includes
...
Many of erdma's includes are redundant, because they are already included
indirectly by kernel headers or custom headers. So we remove all the
unnecessary direct-includes. Besides, add linux/pci.h to erdma.h because
it's also used in the file.

RDMA/erdma: Eliminate unnecessary casting for erdma_post_cmd_wait
...
erdma_post_cmd_wait does not use the 'u64 *req' input parameter directly.
So it is better to define it to 'void *req', and by this we can eliminate
the casting when calling erdma_post_cmd_wait.

RDMA/erdma: Add verbs implementation
...
The RDMA verbs implementation of erdma is divided into three files:
erdma_qp.c, erdma_cq.c, and erdma_verbs.c. Internal used functions and
datapath functions of QP/CQ are put in erdma_qp.c and erdma_cq.c, the rest
is in erdma_verbs.c.
This commit also fixes some static check warnings.
