usb: typec: ucsi: fix probe failure in gaokun_ucsi_probe()
The gaokun_ucsi_probe() uses ucsi_create() to allocate a UCSI instance.
The ucsi_create() validates whether ops->poll_cci is defined, and if not,
it directly returns -EINVAL. However, the gaokun_ucsi_ops structure does
not define the poll_cci, causing ucsi_create() always fail with -EINVAL.
This issue can be observed in the kernel log with the following error:
ucsi_huawei_gaokun.ucsi huawei_gaokun_ec.ucsi.0: probe with driver
ucsi_huawei_gaokun.ucsi failed with error -22
Fix the issue by adding the missing poll_cci callback to gaokun_ucsi_ops.
