85xx: Use proper defines for PCI addresses

We should be using the _MEM_PHYS for LAW and TLB setup and not _MEM_BASE.
While _MEM_BASE & _MEM_PHYS are normally the same, _MEM_BASE should only
be used

85xx: Use proper defines for PCI addresses

We should be using the _MEM_PHYS for LAW and TLB setup and not _MEM_BASE.
While _MEM_BASE & _MEM_PHYS are normally the same, _MEM_BASE should only
be used for configuring the PCI ATMU.

Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections

With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]

For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.

The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.

Reworked FSL Book-E TLB macros to be more readable

The old macros made it difficult to know what WIMGE and perm bits
were set for a TLB entry. Actually use the bit masks for these items
since they are only a single bit.

Also moved the macros into mmu.h out of e500.h since they aren't specific
to e500.

Move the MPC8541/MPC8555/MPC8548 CDS board under board/freescale.

Minor path corrections needed to ensure buildability.
