Subject: [PATCH V5 7/8] mailbox: qcom: Add ipq6018 apcs compatible

The Qualcomm ipq6018 has apcs block, add compatible for the same.
Also, the apcs provides a clock controller functionality similar
to msm8916 but the clock driver is different.

Create a child platform device based on the apcs compatible for the
clock controller functionality.
