Correct initdram to use phys_size_t to represent the size of
dram; instead of changing this all over the place, and correcting
all the other random errors I've noticed, create a
common initdram that is used by all non-corenet 85xx parts.  Most
of the initdram() functions were identical, with 2 common differences:

1) DDR tlbs for the fixed_sdram case were set up in initdram() on
some boards, and were part of the tlb_table on others.  I have
changed them all over to the initdram() method - we shouldn't
be accessing dram before this point so they don't need to be
done sooner, and this seems cleaner.

2) Parts that require the DDR11 erratum workaround had different
implementations - I have adopted the version from the Freescale
errata document.  It also looks like some of the versions were
buggy, and, depending on timing, could have resulted in the
DDR controller being disabled.  This seems bad.

The xpedite boards had a common/fsl_8xxx_ddr.c; with this
change only the 517 board uses this so I have moved the ddr code
into that board's directory in xpedite517x.c

The ATUM8548 board didn't appear to set up any tlbs in the
fixed_sdram case; this patch fixes that.

Having #1 and #2 each as standalone commits might have been
useful as extra bisection points, in the event that anyone runs into
problems -- but I suspect that is a lot of respin work, and hopefully
Things Just Work for most people.

The only other thing I noticed was that...

...right here, the 8540EVAL board bailed out if RAMBOOT was set, thus
bypassing sdram_init.  So this won't strictly match the old behaviour on
at least that board.   Maybe it makes sense to just gut the rest of the
RAMBOOT code (if any) from boards that were doing this, since I
believe it isn't really a globally supported (or at least encouraged)
u-boot feature?

I'm not anywhere near the office at the moment, but later in the week
I'll see if I can find a board (or two?) to test on.

I thought about that, but it turns out that creates a ton of patchery than then just gets whacked out.

Seems OK for POST test on an old MPC8540ADS.  The info printed
for SDRAM kind of interjects itself into the DRAM info, but that is largely
cosmetic.

Testing details of the base commit I used to "am" your patches to are
below.  Feel free to add a Tested-by: from me if you want.

I'll look at making this prettier.... I like pretty.
