This removes in nand.h code that is verbatim duplicated from bbm.h,
including directly bbm.h in nand.h. The previous state of affairs
prevented compiling code for a board hosting both NAND and OneNAND chips.

This patch fixes a problem on systems where the NOR flash is attached
to a 64 bit bus.  The toggle bit detection in flash_toggle() is based
on the assumption that the same flash address is read twice without
any other interjacent flash accesses.  However, on 32 bit systems the
function flash_read64() [as currently implemented] does not perform
an atomic 64 bit read - instead, this is broken down into two 32 bit
read accesses on addresses "addr" and "addr + 4".  So instead of
reading a 64 bit value twice from "addr", we see a sequence of 4 32
bit reads from "addr", "addr + 4", "addr", and "addr + 4".  The
consequence is that flash_toggle() fails to work.

This patch implements a simple, but somewhat ugly solution, as it
avoids the use of flash_read64() in this critical place (by breaking
it down manually into 32 bit read operations) instead of rewriting
flash_read64() such to perform atomic 64 bit reads as one could
expect.  However, such a rewrite would require the use of floating
point load operations, which becomes pretty complex:

	save MSR;
	set Floating Point Enable bit in MSR;
	use "lfd" instruction to perform atomic 64 bit read;
	use "stfd" to store value to temporary variable on stack;
	load u64 value from temporary variable;
	restore saved MSR;
	return u64 value;

The benefit-cost ratio of such an implementation was considered too
bad to actually attempt this, especially as we can expect that such
an implementation would not only have a bigger memory footprint but
also cause a performance degradation.

The patch is following the commit 39243840

mpc86xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache

This is needed in unlock_ram_in_cache() because it is called from C and
will corrupt the small data area anchor that is kept in R2.

lock_ram_in_cache() is modified similarly as good coding practice, but
is not called from C.
