IB/ipath: merge ipath_core and ib_ipath drivers

There is little point in keeping the two drivers separate, so we are
merging them.

This is a low-level driver for QLogic InfiniPath host channel
adapters (HCAs) based on the HT-400 and PE-800 chips.

---help---
This is a driver that provides InfiniBand verbs support for
QLogic InfiniPath host channel adapters (HCAs). This
allows these devices to be used with both kernel upper level
protocols such as IP-over-InfiniBand as well as with userspace
applications (in conjunction with InfiniBand userspace access).
