soc: qcom: spm: Fix idle on THUMB2 kernels
The ifc6410 firmware always enters the kernel in ARM state from
deep idle. Use the cpu_resume_arm() wrapper instead of
cpu_resume() to property switch into the THUMB2 state when we
wake up from idle.
This fixes a problem reported by Kevin Hilman on next-20150601
where the ifc6410 fails to boot a THUMB2 kernel because the
platform's firmware always enters the kernel in ARM mode from
deep idle states.
