ppc4xx: Rename 405gp_pci to 4xx_pci since its used on all 4xx platforms

These files were introduced with the IBM 405GP but are currently used on all
4xx PPC platforms. So the name doesn't match the content anymore. This patch
renames the files to 4xx_pci.c/h.

+ *  09-Sep-98   Created                                                     MCG
+ *  02-Nov-98   Removed External arbiter selected message                   JWB
+ *  27-Nov-98   Zero out PTMBAR2 and disable in PTM2MS                      JWB
+ *  04-Jan-99   Zero out other unused PMM and PTM regs. Change bus scan     MCG
+ *              from (0 to n) to (1 to n).
+ *  17-May-99   Port to Walnut                                              JWB
+ *  17-Jun-99   Updated for VGA support                                     JWB
+ *  21-Jun-99   Updated to allow SRAM region to be a target from PCI bus    JWB
+ *  19-Jul-99   Updated for 405GP pass 1 errata #26 (Low PCI subsequent     MCG
+ *              target latency timer values are not supported).
+ *              Should be fixed in pass 2.
+ *  09-Sep-99   Removed use of PTM2 since the SRAM region no longer needs   JWB
+ *              to be a PCI target. Zero out PTMBAR2 and disable in PTM2MS.
+ *  10-Dec-99   Updated PCI_Write_CFG_Reg for pass2 errata #6               JWB
+ *  11-Jan-00   Ensure PMMxMAs disabled before setting PMMxLAs. This is not
+ *              really required after a reset since PMMxMAs are already
+ * 	        disabled but is a good practice nonetheless.                JWB
+ *  12-Jun-01   stefan.roese@esd-electronics.com
+ *              - PCI host/adapter handling reworked
+ *  09-Jul-01   stefan.roese@esd-electronics.com
+ *              - PCI host now configures from device 0 (not 1) to max_dev,
+ *                (host configures itself)
+ *              - On CPCI-405 pci base address and size is generated from
+ *                SDRAM and FLASH size (CFG regs not used anymore)
+ *              - Some minor changes for CPCI-405-A (adapter version)
+ *  14-Sep-01   stefan.roese@esd-electronics.com
+ *              - CONFIG_PCI_SCAN_SHOW added to print pci devices upon startup
+ *  28-Sep-01   stefan.roese@esd-electronics.com
+ *              - Changed pci master configuration for linux compatibility
+ *                (no need for bios_fixup() anymore)
+ *  26-Feb-02   stefan.roese@esd-electronics.com
+ *              - Bug fixed in pci configuration (Andrew May)
+ *              - Removed pci class code init for CPCI405 board
+ *  15-May-02   stefan.roese@esd-electronics.com
+ *              - New vga device handling
+ *  29-May-02   stefan.roese@esd-electronics.com
+ *              - PCI class code init added (if defined)
