[IA64] hotplug/ia64: SN Hotplug Driver: moving of header files
This patch moves header files out of the arch/ia64/sn directories and into include/asm-ia64/sn. These files were being included by other subsystems and should be under include/asm-ia64/sn. Signed-off-by: Prarit Bhargava <prarit@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

12 * PIC AS DEVICE ZERO
13 * ------------------
14 *
15 * PIC handles PCI/X busses. PCI/X requires that the 'bridge' (i.e. PIC)
16 * be designated as 'device 0'. That is a departure from earlier SGI
17 * PCI bridges. Because of that we use config space 1 to access the
18 * config space of the first actual PCI device on the bus.
19 * Here's what the PIC manual says:
20 *
21 * The current PCI-X bus specification now defines that the parent
22 * hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
23 * reduced the total number of devices from 8 to 4 and removed the
24 * device registers and windows, now only supporting devices 0,1,2, and
25 * 3. PIC did leave all 8 configuration space windows. The reason was
26 * there was nothing to gain by removing them. Here in lies the problem.
27 * The device numbering we do using 0 through 3 is unrelated to the device
28 * numbering which PCI-X requires in configuration space. In the past we
29 * correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
30 * PCI-X requires we start a 1, not 0 and currently the PX brick
31 * does associate our:
32 *
33 * device 0 with configuration space window 1,
34 * device 1 with configuration space window 2,
35 * device 2 with configuration space window 3,
36 * device 3 with configuration space window 4.
37 *
38 * The net effect is that all config space access are off-by-one with
39 * relation to other per-slot accesses on the PIC.
40 * Here is a table that shows some of that:
41 *
42 * Internal Slot#
43 * |
44 * | 0 1 2 3
