ST-Ericsson uses User Interface Boards to extend functionality of
some of their development boards. However, these aren't compatible
with all the supported boards found in Mainline (Snowball for
instance). This patch ensures that the UIBs are only probed on
boards which can actually support them. This in turn saves lots of
unnecessary error messages normally found in Snowball's boot log.

Port is used as an array index before we know if that is proper.
For example, in the catas event case, port is zero; however,
the port index should lie in the range (1..2).
Fix this by using 'port' only in the events where it is of interest.
Test for port out of range in the default (unhandled event) case,

In SRIOV mode, the number of EQs used when computing the total ICM size
was incorrect.
To fix this, we do the following:
1. We add a new structure to mlx4_dev, mlx4_phys_caps, to contain physical HCA
capabilities. The PPF uses the phys capabilities when it computes things
like ICM size.
The dev_caps structure will then contain the paravirtualized values, making
bookkeeping much easier in SRIOV mode. We add a structure rather than a
single parameter because there will be other fields in the phys_caps.
The first field we add to the mlx4_phys_caps structure is num_phys_eqs.
2. In INIT_HCA, when running in SRIOV mode, the "log_num_eqs" parameter
passed to the FW is the number of EQs per VF/PF; each function (PF or VF)
has this number of EQs available.
However, the total number of EQs which must be allowed for in the ICM is
(1 << log_num_eqs) * (#VFs + #PFs). Rather than compute this quantity,
we allocate ICM space for 1024 EQs (which is the device maximum
number of EQs, and which is the value we place in the mlx4_phys_caps structure).
For INIT_HCA, however, we use the per-function number of EQs as described
above.
