rG169e94c41e23: cxgbe(4): Add support for PPOD_EDRAM feature.

Summary

The driver queries the firmware to find out if it supports this feature
and enables it if it does. The firmware moves the iSCSI page pod region
to a lower address so that some of it is located in the faster on-chip
memory instead of external DDR.
