[PATCH v2 4/7] drivers: soc: atmel: add null entry at the end of at91_soc_allowed_list[]

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.

Fixes: 960ddf70cc11 ("drivers: soc: atmel: Avoid calling at91_soc_init on non AT91 SoCs")
