af3a10513c drivers: soc: atmel: add per soc id and version match masks 
SAMA7G5 has different masks for chip ID and chip version on CIDR
register compared to previous AT91 SoCs. For this the commit adapts
the code for SAMA7G5 addition by introducing 2 new members in
struct at91_soc and fill them properly and also preparing the
parsing of proper DT binding.

975435132e 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.

960ddf70cc drivers: soc: atmel: Avoid calling at91_soc_init on non AT91 SoCs 
Since at91_soc_init is called unconditionally from atmel_soc_device_init,
we get the following warning on all non AT91 SoCs:
	" AT91: Could not find identification node"

Fix the same by filtering with allowed AT91 SoC list.
