RDMA/cxgb4: Support on-chip SQs
T4 support on-chip SQs to reduce latency. This patch adds support for
this in iw_cxgb4:
- Manage ocqp memory like other adapter mem resources.
- Allocate user mode SQs from ocqp mem if available.
- Map ocqp mem to user process using write combining.
- Map PCIE_MA_SYNC reg to user process.
Bump uverbs ABI.
