mpc83xx: Add NAND boot support for MPC8315E-RDB boards
The core support for NAND booting is there already, so this patch
is pretty straightforward.
There is one trick though: top level Makefile expects nand_spl to
be in nand_spl/board/$(BOARDDIR), but we can fully reuse the code
from mpc8313erdb boards, and so to not duplicate the code we just
symlink nand_spl/board/freescale/mpc8315erdb to mpc8313erdb.

o silence make during ln echo
o update documentation
o and avoid:
$ ./MAKEALL MPC8315ERDB_NAND
Configuring for MPC8315ERDB board...

/home/r1aaha/git/u-boot/nand_spl/board/freescale/mpc8313erdb/sdram.c:72: undefined reference to `udelay'
by renaming udelay -> __udelay in the spirit of commit
3eb90bad651fab39cffba750ec4421a9c01d60e7 "Generic udelay() with watchdog
support".
