Series interconnect: qcom: sc8180x: Some fixes | expand

Commit Message

Bjorn Andersson May 3, 2022, 9:19 p.m. UTC
The introduction of the Qualcomm SC8180X provider raced with the
refactoring of the RPMh common code and SC8180X was left with the old
style of duplicating the probe function in each provider driver.

Transition the driver to the "new" design.
