[PATCH v8 0/3] PM / AVS: SVS: Introduce SVS engine

[Roger Lu]

1. SVS driver use OPP adjust event in [1] to update OPP table voltage part.
2. SVS dts node refers to CPU opp table [2] and GPU opp table [3].
3. SVS and thermal dts use the same thermal efuse [4].
4. SVS dts needs power-domain [5][6] and PMIC regulator [7].

changes since v7:
- Add "mtk_svs.yaml" for device-tree binding document.
- Add svs_add_thermal_device_link() in driver for svs device (consumer)
to link thermal device (supplier).
- replace pm_qos_add_request() with cpu_latency_qos_add_request() for
letting CPUs leave idle-off state.
