soc: qcom: pmic_glink: disable UCSI on sc8280xp 

Enabling UCSI on sc8280xp and the Lenovo ThinkPad X13s in particular
results in a number of errors and timeouts during boot:

[    9.012421] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: GET_CONNECTOR_STATUS failed (-95)
[   14.047379] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: timeout waiting for UCSI sync write response
[   14.050708] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: GET_CONNECTOR_STATUS failed (-110)
[   20.192382] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: timeout waiting for UCSI sync write response
[   20.192542] ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: GET_CONNECTOR_STATUS failed (-110)

Disable UCSI on sc8280xp until this has been resolved.
