[PATCH] I2O: new sysfs attributes and Adaptec specific block device access and 64-bit DMA support

Changes:
 - Added Bus-OSM which could be used by user space programs to reset a
   channel on the controller
 - Make ioctl's in Config-OSM obsolete in prefer for sysfs attributes and
   move those to its own file
 - Added sysfs attribute for firmware read and write access for I2O
   controllers
 - Added special handling of firmware read and write access for Adaptec
   controllers
 - Added vendor id and product id as sysfs-attribute to Executive classes
 - Added automatic notification of LCT change handling to Exec-OSM
 - Added flushing function to Block-OSM for later barrier implementation
 - Use PRIVATE messages for Block access on Adaptec controllers, which are
   faster then BLOCK class access
 - Cleaned up support for Promise controller
 - New messages are now detected using the IRQ status register as
   suggested by the I2O spec
 - Added i2o_dma_high() and i2o_dma_low() functions
 - Added facility for SG tablesize calculation when using 32-bit and
   64-bit DMA addresses
 - Added i2o_dma_map_single() and i2o_dma_map_sg() which could build the
   SG list for 32-bit as well as 64-bit DMA addresses
