[PATCH] Fusion-MPT Update (2.03.01.01)

This upgrades the Fusion-MPT driver from 2.03.00.02 to 2.03.01.01.

Bug Fixes:
 o Added back missing queuecommand entry point define ?!
 o Added to code to break marriage of two controllers during unload
  (could cause a panic)
 o SCSI driver will de-register with base driver if no SCSI-capable
   adapters found

Minor Changes:
 o Removed errant spaces at ends of lines  (most of the changes)
 o Moved code around (and in-lined) some functions for performance reasons.
 o Modified /proc functionality to facilitate testing with 2.5
 o Added a call to synchronize_irq on unload (HP request)
 o Modified load of base to close a potential hole
 o Added code to set the FW IO coalescing depth (IBM request)
 o Changed return when mptctl driver registration fails (Kernel.org request)
 o SCSI driver detect routine calls a generic spinlock for all kernels
   (Kernel.org request)
 o Controller RAID page dynamic instead of static

Currently running a multi-disk stress test w/ 2.5.53,  this patch and driver
built-in. Verified basic reset handling is working properly.
