Fix @ -> <at> substitution

When applying the AT91CAP9 patches upstream, something transformed
the '@' character into the ' <at> ' sequence.

The patch below restores the original form in all the places where
it has been modified (the AT91CAP9 files, the AT91SAM9260 files which
were copied from AT91CAP9, and a couple of other files where the
' <at> ' sequence was present).

     The ft_cpu_setup() function in mpc8641hpcn.c should have been
     removed earlier as it was under the obsolete CONFIG_OF_FLAT_TREE,
     but was missed.  Only, the sbc8641d was nominally still using it.
