This patch creates a memory map with all the devices
in 36-bit physical space, in addition to the 32-bit map.
The CCSR relocation is moved (again, sorry) to
allow for the physical address to be 36 bits - this
requires translation to be enabled. With 36-bit physical
addressing enabled, we are no longer running with VA=PA
translations. This means we have to distinguish between
the two in the config file. The existing region name is
used to indicate the virtual address, and a _PHYS variety
is created to represent the physical address.
Large physical addressing is not enabled by default.
Set CONFIG_PHYS_64BIT in the config file to turn this on.

The memory map on the 8641hpcn is modified to look more like
the 85xx boards; this is a step towards a more standardized
layout going forward. As part of this change, we now relocate
the flash.
The regions for some of the mappings were far larger than they
needed to be. I have reduced the mappings to match the
actual sizes supported by the hardware.
In addition I have removed the comments at the head
of the BAT blocks in the config file, rather than updating
them. These get horribly out of date, and it's a simple
matter to look at the defines to see what they are set to
since everything is right here in the same file.
Documentation has been changed to reflect the new map, as this
change is user visible, and affects the OS which runs post-uboot.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

Move the 8641HPCN's PIXIS code to the new directory
board/freescale/common/ as it will be shared by
future boards not in the same processor family.
Write a "pixis_reset" command that utilizes the FPGA
reset sequencer to support alternate soft-reset options
such as using the "alternate" flash bank, enabling
the watch dog, or choosing different CPU frequencies.
Add documentation for the pixis_reset to README.mpc8641hpcn.
