arm64: dts: qcom: msm8939: revert use of APCS mbox for RPM
Commit 22e4e43484c4 ("arm64: dts: qcom: msm8939: Use mboxes
properties for APCS") broke the boot on msm8939 platforms.
The issue comes from the SMD driver failing to request the mbox
channel because of circular dependencies:
1. rpm -> apcs1_mbox -> rpmcc (RPM_SMD_XO_CLK_SRC) -> rpm.
2. rpm -> apcs1_mbox -> gcc -> rpmcc (RPM_SMD_XO_CLK_SRC) -> rpm
3. rpm -> apcs1_mbox -> apcs2 -> gcc -> rpmcc (RPM_SMD_XO_CLK_SRC) -> rpm
To fix this issue let's switch back to using the deprecated
qcom,ipc property for the RPM node.
