Henry Martin d62a589eaa soc: aspeed: Add NULL check in aspeed_lpc_enable_snoop() 
[ Upstream commit f1706e0e1a ]

devm_kasprintf() returns NULL when memory allocation fails. Currently,
aspeed_lpc_enable_snoop() does not check for this case, which results in a
NULL pointer dereference.

Add NULL check after devm_kasprintf() to prevent this issue.
