Impact: new features
based on patch on
http://marc.info/?l=linux-ide&m=116289338705418&w=2
1. update the patch for 2.6.19 to latest upstream ( 2.6.28?)
2. fix shared sgpio to support several mcp55 + io55, so every mcp55 have
seperate spinlock
3. use scratch_source as numbering of sgpio instead of address of struct,
so could go through kexec/kdump
v2: revert NV_ON and NV_OFF, so turn on Activity LED all the time when disk is idle.
v3: use one timer per sgpio instead of per nv_host, so for mcp55+io55 system will use 2 timers
instead of 6 timers.
