c815d769b5 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.

c6a8b171ca mailbox: qcom: Convert APCS IPC driver to use regmap 
This hardware block provides more functionalities that just IPC. Convert
it to regmap to allow other child platform devices to use the same regmap.

This implements a driver that exposes the IPC bits found in the APCS
Global block in various Qualcomm platforms. The bits are used to signal
inter-processor communication signals from the application CPU to other
masters.
