There are two parts of changes. The first is just enable
PCI in Makefiles and in Kconfig. The second is the rest of
missing files. I didn't want to add it with previous patch
because that patch is too big.

Current Microblaze toolchain has problem with weak symbols
that's why is necessary to apply this changes to be possible
to compile pci support.
Xilinx knows about this problem.

We need to define _PAGE_FILE macro and change pte
functions. Microblaze use the same MMU as PowerPC
that's why we define _PAGE_FILE in the same style.
This change fixed remap_file_pages01 LTP test.

Some device drivers call this, so add a macro
that pretends to do this. Since there is no
MMU support, it won't actually result in an
uncached mapping, though.
