Hide typec ACPI device if UCSI is supported

We need to remove the ACPI table entry associated with the cros_ec_typec
driver once we switch to the UCSI kernel driver. The logic to remove the
ACPI device is

1) Check if EC implements a PPM using a feature flag.
2) During the transition to the new kernel driver, check if CBI flag to
enable UCSI is set.

b/333074788 and https://crrev.com/c/5421069 track the corresponding EC
change to add CBI.
https://crrev.com/c/5416841 is the change for adding the feature flag
