[U-Boot] [PATCH v2] mpc8xxx: improve LAW error messages when setting up DDR

[Paul Gortmaker <paul.gortmaker@windriver.com>]

When setting up the LAWs for the DDR, if there was an error,
you got the not-so-helpful error text "ERROR" and nothing
else.  Not only is it non-informative, but it is also
pretty frustrating trying to grep for "ERROR" in the source.

v2: sync ctrl #'s; use __func__ as per Peter's comments.
