fsl_pci_init - Remove self PCSRBAR allocation
CPU physical address space was being wasted by allocating a PCSRBAR PCI inbound region to it's memory space. As a rule, PCSRBAR should be left alone since it does not affect transactions from self and other masters may have changed it. Signed-off-by: Ed Swarthout <ed.swarthout@freescale.com>
