This fix changes the opcode relative counters for receive to per
context.

Profiling has shown that when mulitple contexts are being used there
is a lot of cache activity associated with these counters.

The code formerly kept these counters per port, but only provided the
interface to read per HCA.  This patch converts the read of counters
to per HCA and adds the debugfs hooks to be able to read the file as a
sequence of opcodes.

Extract the microcode for the QLogic QLE7220 series IB HCA and use the
kernel microcode request facility to load the microcode.  This
supports Debian Linux's requirements to separate microcode which
doesn't have open source code available from the device driver.
