IB/ehca: Serialize HCA-related hCalls if necessary
Several pSeries firmware versions share a rare locking issue in the
HCA-related hCalls. Check for a feature flag that indicates the issue
being fixed and serialize all HCA hCalls if not.

IB/ehca: Return physical link information in query_port()
Newer firmware versions return physical port information to the
partition, so hand that information to the consumer if it's present.

IB/ehca: add Shared Receive Queue support
Support SRQs on eHCA2. Since an SRQ is a QP for eHCA2, a lot of code
(structures, create, destroy, post_recv) can be shared between QP and SRQ.

IB/ehca: HW level, HW caps and MTU autodetection
In preparation for support of new eHCA2 features, change adapter probing:
- Hardware level is changed to encode major and minor chip version
- Hardware capabilities are queried from the firmware
- The maximum MTU is queried from the firmware instead of assuming a
fixed value
