Bug Description
[Impact]
USB Type-C ports would not be seen at ls /sys/class/typec/ some times, ie, driver probe would fail. The fix just changes a timeout setting, allowing the probe to succeed in those cases there is load on the system.
[Test Case]
During boot, with the system at load, the probe would fail some times. With the increased timeout for firmware responses, that doesn't happen after many reboots.
[Regression Potential]
This would only impact systems that have this specific ACPI node. As the probe runs on a work queue, this should not impact boot time.

this should be a regression issue.
