libpayload/i8042: Increase response timeout to 1.5s
The current timeout of 500ms is too low. For instance self-test of the KBC integrated into IT8516E took almost 1s in tests. We already check for presence of the KBC before the self-test. So the timeout should only trigger on a hardware defect and we can leave some margin.
