1) Removing chio, rcmd, restore, scsictl, shutdown and slattach
from the ramdisk images
2) Removing the isp* driver from the INSTALL kernel configs
3) Reducing the memory disk and ramdisk size back from 4400 to 4200 blocks
As a result, also remove mention as QLogic ISP controllers as being
supported by the installation.
With this, the INSTALL kernel images should once again be usable;
the firmware apparently imposes a size limit around 5MB on the files
it will load.
Longer-term, this port probably ought to get it's own stand-alone boot
loader, so that it might use e.g. loadable modules.
