AMD/CIMx: Add functions for AMD PCI IRQ routing
This change also moves the PCI INT functions to
southbridge/amd so that they can be used by CIMX and
AGESA. The amd/persimmon board is updated for this
change.

The PCI_INTR table is an Index/Data pair of I/O ports
0xC00 and 0xC01. This table is responsible for physically
routing IRQs to the PIC and IOAPIC. The settings given
in this table are chipset and mainboard dependent, so the
table values will reside in the mainboard.c file. This
allows for a system to uniquely set its IRQ routing.
The function to write the PCI_INTR table resides in
cimx_util.c because the indices into the table have
the same definitions for all SBx00 FCH chipsets.
The next piece is a function that will read the PCI_INTR
table and program the INT_LINE and INT_PIN registers in
PCI config space appropriately. This function will read
a devices' INT_PIN register, which is always hardcoded to
a value if it uses hardware interrupts. It then uses this
value, along with the device and function numbers to
determine an index into the PCI_INTR table. It will read
the table and program the corresponding value into the PCI
config space register 0x3C, INT_LINE. Finally, it will set
this IRQ number to LEVEL_TRIGGERED on the PIC because it is
a PCI device interrupt and the must be level triggered.
For example, the SB800 USB EHCI device 0:18.2 has an INT_PIN
value hardcoded to 2. This corresponds to PIN B. On the
Persimmon mainboard, I want the USB device to use IRQ 11. I
will program the PCI_INTR table at index 0x31 (this USB device
index) to 11. This function will then read the INT_PIN register,
read the PCI_INTR table, and then program the INT_LINE register
with the value it read. It will then set the IRQ on the PIC to
LEVEL_TRIGGERED by writing a 1 to I/O port 0x4D1 at bit position 4.
Also, the SB700 has slightly different register definitions than
the newer SB800 and SB900 so it needs its own set of #defines for
the pci_intr registers.
Only the Persimmon mainboard is adapted to this change as an
example for other mainboards.

These are the PMIO & PMIO2 read & write routines from
src/southbridge/amd/sb800/sb800.c & sb800.h for use in the cimx
tree. Currently most platforms using CIMX are calling WritePMIO()
directly from the src/vendorcode/amd/cimx/sbX00 directories
instead of using a wrapper function.
These functions only do byte reads & writes.
