drivers: soc: atmel: add null entry at the end of at91_soc_allowed_list[]

commit 680896556805d3ad3fa47f6002b87b3041a45ac2 upstream.

of_match_node() calls __of_match_node() which loops though the entries of
matches array. It stops when condition:
(matches->name[0] || matches->type[0] || matches->compatible[0]) is
false. Thus, add a null entry at the end of at91_soc_allowed_list[]
array.
