[U-Boot-Users] [PATCH] fsl_pci_init - Remove self PCSRBAR allocation

[Ed Swarthout <ed.swarthout@hwdebug.com>]

From: Ed Swarthout <Ed.Swarthout@freescale.com>

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.

Was: {PATCH] Fix MPC8544DS PCIe3 scsi.

This fixes the MPC8544DS scsi error: 

SCSI:  scanning bus for devices...
Invaild port number 1
Invaild port number 2
Invaild port number 3

when not enough PCIe3 memory space is available for allocation.

This replaces k's temp hack.
