Simplify ehca_encode_hwpage_size(), fixing an infinite loop for pgsize == 0
in the process. Fix the bug in alloc_fmr() that triggered the loop.

ehca_shca.hca_cap_mr_pgsize now contains all supported page sizes ORed
together. This makes some checks easier to code and understand, plus we can
return this value verbatim in query_hca(), fixing a problem with SRP
(reported by Anton Blanchard -- thanks!).

This patch enhances ehca with a capability to autodetect the ports being
connected physically. In order to utilize that function the module option
nr_ports must be set to -1 (default is 2 - two ports). This feature is
experimental and will made the default

The IPD formula was a little off and assumed a fixed physical link rate; fix
the formula and query the actual physical link rate, now that we can get it.
Also, refactor the calculation into a common function ehca_calc_ipd() and
use that instead of duplicating code.
