ARM: orion5x: clean up mach/*.h headers

This is a simple move of all header files that are no longer
included by anything else from the include/mach directory
to the platform directory itself as preparation for
multiplatform support.

The mach/uncompress.h headers are left in place for now,
and are mildly modified to be independent of the other
headers. They will be removed entirely when ARCH_MULTIPLATFORM
gets enabled and they become obsolete.

Rather than updating the path names inside of the comments
of each header, I delete those comments to avoid having to
update them again, should they get moved or copied another
time.

ARM: orion5x: convert d2net to Device Tree

This commit converts the LaCie d2 Network platform to the Device Tree.

All devices except LEDs are converted, because the LED code needs a
non-LED GPIO to be set to a given value for the LEDs to work, and this
cannot yet be easily represented in DT.

Also, references to the LaCie Big Disk Network platform are lost,
because this platform apparently has exactly the same hardware support
as the LaCie d2 Network, so their Device Tree files would be
identical.
