Peter Tyser 8ca78f2c89 fsl: Clean up printing of PCI boot info
Previously boards used a variety of indentations, newline styles, and
colon styles for the PCI information that is printed on bootup.  This
patch unifies the style to look like:

...
NAND:  1024 MiB
PCIE1: connected as Root Complex
           Scanning PCI bus 01
        04  01  8086  1010  0200  00
