Before IBA7220 support was added, the ipath driver didn't support any
hardware unless PCI_MSI and/or HT_IRQ was enabled.  However, the
IBA7220 can generate INTx interrupts, so it makes sense to allow the
driver to be build even if PCI_MSI=n and HT_IRQ=n.

Change Kconfig objects from "menu, config" into "menuconfig" so
that the user can disable the whole feature without having to
enter the menu first.

The PCI Express and Hypertransport chip-specific source files should only
be built when the kernel has the capability of actually compiling them.

This fixes the driver build on, for example, ia64.

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