RDMA/erdma: Minor refactor of device init flow
...
After necessary configuration, driver should wait hardware finishing
initialization. The wait sets at CMDQ related function though it has
nothing to do with CMDQ. Refactor this part to make code cleaner.

RDMA/erdma: Eliminate unnecessary casting of EQ doorbells
...
Using void * to define EQ doorbell pointer can eliminate unnecessary
casting when performing assignment. Also rename *db_addr* to *db* for a
shorter name.

RDMA/erdma: Unify byte ordering APIs usage
...
Replace __be32_to_cpu/__cpu_to_be16 with be32_to_cpu/cpu_to_be16.
And use be32_to_cpu_array to copy and swap byte order to hide the
loop.

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 cmdq implementation
...
Cmdq is the main control plane channel between erdma driver and hardware.
After erdma device is initialized, the cmdq channel will be active in the
whole lifecycle of this driver.
This commit also includes two modifications from Christophe, one is using
the bitmap API to allocate bitmaps instead of hand-writing, and another
is using the non-atomic bitmap API when applicable.
