8548cds PCIE support.

Make the early L1 cache stack region guarded to prevent speculative
fetches outside the locked range.

Use _PHYS defines, not _MEM for cpu-side PCI memory mapped regions.
init.S whitespace cleanup.

Allow TEXT_BASE value to be specified on command line.  This allows it
to be set to 0xfffc0000 which cuts the uboot binary in half.

Clear and enable lbc and ecm errors.

Update last_busno in device-tree for pci and pcie.

Remove load of obsolete cpu/mpc85xx/pci.0
