[SCSI] ipr: update the configuration table code for the next generation chip

This patch changes the configuration table structures and related code such
that both 32 bit and 64 bit based adapters can work with the driver.

This patch also implements the code to generate the virtual bus/id/lun values
for devices connected to the new adapters.  It also implements support for the
new device resource path.
