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 PMIC regulator [5].

Therefore, change SVS pm_ops to prepare/complete. - Add high temperature voltages compensation codes. - Add irqflags in "struct svs_platform" for supporting different SVS HW setting. - Set signed-off voltages to system when system suspend. - Add SVS HW reset flag for future SVS HW support. - Coding style refinement.
