Remove legacy NAND and disk on chip code.

Legacy NAND had been scheduled for removal.  Any boards that use this
were already not building in the previous release due to an #error.

The disk on chip code in common/cmd_doc.c relies on legacy NAND,
and it has also been removed.  There is newer disk on chip code
in drivers/mtd/nand; someone with access to hardware and sufficient
time and motivation can try to get that working, but for now disk
on chip is not supported.

-/* CONFIG_SYS_DOC_PASSIVE_PROBE:
-   In order to ensure that the BIOS checksum is correct at boot time, and
-   hence that the onboard BIOS extension gets executed, the DiskOnChip
-   goes into reset mode when it is read sequentially: all registers
-   return 0xff until the chip is woken up again by writing to the
-   DOCControl register.
-
-   Unfortunately, this means that the probe for the DiskOnChip is unsafe,
-   because one of the first things it does is write to where it thinks
-   the DOCControl register should be - which may well be shared memory
-   for another device. I've had machines which lock up when this is
-   attempted. Hence the possibility to do a passive probe, which will fail
-   to detect a chip in reset mode, but is at least guaranteed not to lock
-   the machine.
-
-   If you have this problem, uncomment the following line:

-		   polynomial form -> index form  index_of[j=alpha**i] = i
-   alpha=2 is the primitive element of GF(2**m)
-   HARI's COMMENT: (4/13/94) alpha_to[] can be used as follows:
-	Let @ represent the primitive element commonly called "alpha" that
-   is the root of the primitive polynomial p(x). Then in GF(2^m), for any
-   0 <= i <= 2^m-2,
-	@^i = a(0) + a(1) @ + a(2) @^2 + ... + a(m-1) @^(m-1)
-   where the binary vector (a(0),a(1),a(2),...,a(m-1)) is the representation
-   of the integer "alpha_to[i]" with a(0) being the LSB and a(m-1) the MSB. Thus for
-   example the polynomial representation of @^5 would be given by the binary
-   representation of the integer "alpha_to[5]".
-		   Similarily, index_of[] can be used as follows:
-	As above, let @ represent the primitive element of GF(2^m) that is
-   the root of the primitive polynomial p(x). In order to find the power
-   of @ (alpha) that has the polynomial representation
-	a(0) + a(1) @ + a(2) @^2 + ... + a(m-1) @^(m-1)
-   we consider the integer "i" whose binary representation with a(0) being LSB
-   and a(m-1) MSB is (a(0),a(1),...,a(m-1)) and locate the entry
-   "index_of[i]". Now, @^index_of[i] is that element whose polynomial
-    representation is (a(0),a(1),a(2),...,a(m-1)).
-   NOTE:
-	The element alpha_to[2^m-1] = 0 always signifying that the
-   representation of "@^infinity" = 0 is (0,0,0,...,0).
-	Similarily, the element index_of[0] = A0 always signifying
-   that the power of alpha which has the polynomial representation
-   (0,0,...,0) is "infinity".
