IB/uverbs: Move part of enum ib_device_cap_flags to uapi

1) Part of enum ib_device_cap_flags are used by ibv_query_device(3)
   or ibv_query_device_ex(3), so we define them in
   include/uapi/rdma/ib_user_verbs.h and only expose them to userspace.

2) Reformat enum ib_device_cap_flags by removing the indent before '='.
