This adds arch support for PPC mpc83xx to boot "minimal" (4K) SPLs
using the new infrastructure.

Existing nand_spl targets are updated to deal with the name change
from nand_init.c to spl_minimal.c (as in theory this isn't limited
to NAND anymore).

This was already used by some SPL targets, and allows the pad amount to
be specified by board config headers rather than only in makefile
fragments.

Also supply a pad-to of zero if the variable is undefined.  It works
without this, but this avoids relying on undocumented behavior.

Currently just validates variable types as decimal, hexidecimal,
boolean, ip address, and mac address.  Call
env_acl_validate_setenv_params() from setenv() in fw_env.c.

If the entry is not found in the env .flags, then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.

Move the read of the old value to inside the check function.  In some
cases it can be avoided all together and at the least the code is only
called from one place.

Also name the function and the callback to more clearly describe what

Pass the ENTRY instead of just the name for direct access to the whole
data structure.

Pass an enum to the callback that specifies the operation being approved.
