[IA64] Move include/asm-ia64 to arch/ia64/include/asm
After moving the the include files there were a few clean-ups:
1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h>
2) Some comments alerted maintainers to look at various header files to
make matching updates if certain code were to be changed. Updated these
comments to use the new include paths.
3) Some header files mentioned their own names in initial comments. Just
deleted these self references.

Because of that we use config space 1 to access the - * config space of the first actual PCI device on the bus. - * Here's what the PIC manual says: - * - * The current PCI-X bus specification now defines that the parent - * hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC - * reduced the total number of devices from 8 to 4 and removed the - * device registers and windows, now only supporting devices 0,1,2, and - * 3. PIC did leave all 8 configuration space windows. The reason was - * there was nothing to gain by removing them. Here in lies the problem. - * The device numbering we do using 0 through 3 is unrelated to the device - * numbering which PCI-X requires in configuration space. In the past we - * correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc. - * PCI-X requires we start a 1, not 0 and currently the PX brick - * does associate our: - * - * device 0 with configuration space window 1, - * device 1 with configuration space window 2, - * device 2 with configuration space window 3, - * device 3 with configuration space window 4. - * - * The net effect is that all config space access are off-by-one with - * relation to other per-slot accesses on the PIC. - * Here is a table that shows some of that: - * - * Internal Slot# - * | - * | 0 1 2 3 - * ----------|--------------------------------------- - * config | 0x21000 0x22000 0x23000 0x24000 - * | - * even rrb | 0[0] n/a 1[0] n/a [] == implied even/odd - * | - * odd rrb | n/a 0[1] n/a 1[1] - * | - * int dev | 00 01 10 11 - * | - * ext slot# | 1 2 3 4 - * ----------|--------------------------------------- - */ - -#define PIC_ATE_TARGETID_SHFT 8 -#define PIC_HOST_INTR_ADDR 0x0000FFFFFFFFFFFFUL -#define PIC_PCI64_ATTR_TARG_SHFT 60 - - -/***************************************************************************** - *********************** PIC MMR structure mapping *************************** - *****************************************************************************/ - -/* NOTE: PIC WAR.
