Make MPC8641's PCI/PCI-E driver a common driver for many FSL parts.
All of the PCI/PCI-Express driver and initialization code that was in the MPC8641HPCN port has now been moved into the common drivers/fsl_pci_init.c. In a subsequent patch, this will be utilized by the 85xx ports as well. Common PCI-E IMMAP register blocks for FSL 85xx/86xx are added. Also enable the second PCI-Express controller on 8641 by getting its BATS and CFG_ setup right. Fixed a u16 vendor compiler warning in AHCI driver too.
