mailbox: qcom: Create APCS child device for clock controller
There is a clock controller functionality provided by the APCS hardware
block of msm8916 devices. The device-tree would represent an APCS node
with both mailbox and clock provider properties.
Create a platform child device for the clock controller functionality so
the driver can probe and use APCS as parent.
