From this driver's point of view the major new thing is that the
GRPCI peripheral PCI bridge has been updated to GRPCI2, the second
version. This means that both Big and Little Endian systems are now
supported and autodetected on runtime.

The PCI frequency is used as AMBA frequency of the GR-RASTA-TMTC.

Before the LIBPCI didn't probe device0 (AD16), the host bridge
drivers used bus=dev=func=0 to internally probe the host bridge's
target interface. Now that LIBPCI uses bus=dev=func=0 to access
device0, bus=0xff is introduced internally to identify the
host bridge target configuration space.

In some GRPCI cores not setting the cache line size could result
in long prefetches on the AMBA bus which would lead to bad
performance when doing PCI reads to GRPCI target interface (DMA).

The CCHIP driver is replaced with the GR_701 driver. The
RASTA driver is replaced by the GR-RASTA-IO driver.
All drivers are now compatible with both LEON2 and LEON3,
drivers were initialized directly by the PCI-board drivers
are now initialized by the driver manager and therefore
does not require the double code created by including for
example grcan.c into grcan_rasta.c. The other drivers needs
to be updated to the driver manager framework however.
Added support for:
* GR-701 (only LEON2 before)
* GR-RASTA-IO (only LEON2 before)
* GR-RASTA-ADCDAC
* GR-RASTA-TMTC
* GR-RASTA-SPW-ROUTER
* GR-TMTC-1553

The old code used a limited PCI configuration library, which was
duplicated into LEON2 and LEON3 BSP pci.c together with respective
Host controller PCI interface.
The LEON2 BSP had support for AT697 PCI, and LEON3 for GRPCI PCI
Host controller. With this update new PCI Host drivers are added,
and all support the new generic PCI Library:
* AT697 PCI (LEON2 only)
* GRPCI (LEON2-GRLIB and LEON3)
* GRPCI2 (LEON2-GRLIB and LEON3)
* Actel PCIF GRLIB Wrapper (LEON3 only)
The LEON2 BSP is defined as big-endian PCI in bsp.h, since the
AT697 supports only big-endian PCI.

+ libbsp/sparc/shared/include/pci.h was largely a copy of
an older version of the cpukit pci.h. Removed much of the
contents and included <rtems/pci.h>.
+ sparc/*/pci*.c - Move to <rtems/pci.h> required updating
to use uint32_t for dword accesses.
+ Rename PCI_MULTI_FUNCTION to PCI_HEADER_TYPE_MULTI_FUNCTION
+ Define PCI_HEADER_TYPE_MULTI_FUNCTION in cpukit pci.h and remove
PCI_MULTI_FUNCTION definitions in C files.
+ Move PCI_INVALID_VENDORDEVICEID definitions from various C files
to cpukit pci.h

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.
