drivers: soc: atmel: Avoid calling at91_soc_init on non AT91 SoCs

Browse Source 
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.
