Subject: [PATCH 0/7] Use mboxes instead of syscon for APCS (arm32 & arm64)

The first patch is for removing a bogus error warning I've noticed while
developing this on msm8226 - there the patches are also coming later for
this SoC since apcs is getting hooked up to cpufreq there also.

Apart from usages from the qcom,smsm driver (patches coming!) all other
usages of the apcs mailbox now go via the mailbox driver - where one is
used, so some arm32 boards will continue using "qcom,ipc*" properties in
the short or long term.

Only compile-tested apart from msm8953 (tested on sdm632-fairphone-fp3)
and msm8974 (tested on msm8974pro-fairphone-fp2), but I don't expect any
complications with this.
