soc: aspeed: Add NULL check in aspeed_lpc_enable_snoop()
[ Upstream commit f1706e0e1a74b095cbc60375b9b1e6205f5f4c98 ]
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.
