RDMA/erdma: Report atomic capacity when hardware supports atomic feature
Introduce "capacity flags" field at where hardware put all zeros originally
in "query device" response. Using this field, hardware can report atomic
feature if supports.

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.
