[PATCH] I2O: second code cleanup of sparse warnings and unneeded syncronization

Changes:
 - Added header "core.h" for i2o_core.ko internal definitions
 - More sparse fixes
 - Changed display of TID's in sysfs attributes from XXX to 0xXXX
 - Use the right functions for accessing I/O and normal memory
 - Removed error handling of SCSI device errors and let the SCSI layer
   take care of it
 - Added new device / removed device handling to SCSI-OSM
 - Make status access volatile
 - Cleaned up activation of I2O controller
 - Removed unnecessary wmb() and rmb() calls
 - Use own struct i2o_io for I/O memory instead of struct i2o_dma
