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.

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.

To simplify machine init and as the soc_device struct is not used as the
parent for on-chip devices anymore, move SoC detection to its own driver.
