[PATCH v3 0/3] Add smp booting support for Qualcomm ARMv8 SoCs

[Kumar Gala]

This patch set adds support for SMP boot on the MSM8x16 family of Qualcomm SoCs.

To support SMP on the MSM8x16 SoCs we need to add ARMv8/64-bit SCM interfaces to
setup the boot/release addresses for the secondary CPUs.  In addition we need
a uniquie set of cpu ops.  I'm aware the desired methods for booting secondary
CPUs is either via spintable or PSCI.  However, these SoCs are shipping with a
firmware that does not support those methods.

TODO:
* clean up docs related to 'qcom,arm-cortex-acc' and L2

v3:
* dropped use of pen, just release CPUs directly into secondary_start

v2:
* Dropped introduction and use of CPU_METHOD_OF_DECLARE
* Moved qcom cpu ops from drivers/soc/qcom to arch/arm64/kernel
* Renamed msm to qcom in cpu ops code, minor cleans (remove dead defines/code)
