base: soc: Check for NULL SoC device attributes If soc_device_match() is used to check the value of a specific attribute that is not present for the current SoC, the kernel crashes with a NULL pointer dereference. Fix this by explicitly checking for the absence of a needed property, and considering this a non-match.
