GENIO: cpufreq: mediatek: correct max sram voltage for MT8365

Since the regulator cannot be set to 940mV, it will cause an error message. Adjust it to 925mV to meet the regulator's requirements.

BACKPORT: UPSTREAM: soc: mediatek: pm-domains: Add buck isolation setting in power domain

In some chipsets, we need to disable EXT_BUCK_ISO before turning on the specific power pm-domains (mtcmos), such as ADSP in MT8192 and CAM_VCORE in MT8188.

Add the MTK_SCPD_EXT_BUCK_ISO flag to control the buck isolation setting in the mediatek power domain driver.

cpufreq: mediatek: Add opp notification support

From this opp notifier, cpufreq should listen to opp notification and do proper actions when receiving events of disable and voltage adjustment.

One of the user for this opp notifier is MediaTek SVS. The MediaTek Smart Voltage Scaling (SVS) is a hardware which calculates suitable SVS bank voltages to OPP voltage table.

cpufreq: mediatek: Refine mtk_cpufreq_voltage_tracking()

Because the difference of sram and proc should in a range of min_volt_shift and max_volt_shift. We need to adjust the sram and proc step by step.

We replace VOLT_TOL (voltage tolerance) with the platform data and update the logic to determine the voltage boundary and invoking regulator_set_voltage.

Use 'sram_min_volt' and 'sram_max_volt' to determine the voltage boundary of sram regulator.
Use (sram_min_volt - min_volt_shift) and 'proc_max_volt' to determine the voltage boundary of vproc regulator.

Moreover, to prevent infinite loop when tracking voltage, we calculate the maximum value for each platform data. We assume min voltage is 0 and tracking target voltage using min_volt_shift for each iteration. The retry_max is 3 times of expeted iteration count.

cpufreq: mediatek: Unregister platform device on exit

We register the platform device when driver inits. However, we do not unregister it when driver exits.

To resolve this, we declare the platform data to be a global static variable and rename it to be "cpufreq_pdev". With this global variable, we can do platform_device_unregister() when driver exits.

For some MediaTek SoCs, like MT8186, it's possible that the sram regulator is shared between CPU and CCI. We hope regulator framework can return error for error handling rather than a dummy handler from regulator_get api. Therefore, we choose to use regulator_get_optional.
