ppc4xx: Set default PCI device ID for 405EP boards

Current code only sets the PCI vendor id to 0x1014 and
leaved device id to 0x0000.

Ths patch ....
a) uses the correct PCI_VENDOR_ID_IBM macro for this
b) sets the default device ID as stated in the UM to 0x0156
   by using PCI_DEVICE_ID_IBM_405GP for this.
