soc: mediatek: Add PMIC wrapper for MT8135 and MT8173 SoCs This adds support for the PMIC wrapper found on MediaTek MT8135 and MT8173 SoCs. The PMIC wrapper is found on MT6xxx SoCs aswell but these are currently not supported. On MediaTek MT8135, MT8173 and other SoCs the PMIC is connected via SPI. The SPI master interface is not directly visible to the CPU, but only through the PMIC wrapper inside the SoC. The communication between the SoC and the PMIC can optionally be encrypted. Also a non standard Dual IO SPI mode can be used to increase speed. The MT8135 also supports a special feature named "IP Pairing". With IP Pairing the pins of some SoC internal peripherals can be on the PMIC. The signals of these pins are routed over the SPI bus using the pwrap bridge. Because of these optional non SPI conform features the PMIC driver is not implemented as a SPI bus master driver.

soc: mediatek: place Kconfig for all SoC drivers under menu Add cleanup for placing all Kconfig for all MediaTek SoC drivers under the independent menu as other SoCs vendor usually did. Since the menu would be shown depending on "ARCH_MEDIATEK || COMPILE_TEST" selected and MTK_PMIC_WRAP is still safe compiling with the case of "COMPILE_TEST" only, the superfluous dependency for those items under the menu also is also being removed for the sake of simplicity.

Say yes here to add support for the MediaTek Command Queue (CMDQ)
driver. The CMDQ is used to help read/write registers with critical

soc: Mediatek: Add SCPSYS power domain driver This adds a power domain driver for the Mediatek SCPSYS unit. The System Control Processor System (SCPSYS) has several power management related tasks in the system. The tasks include thermal measurement, dynamic voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control. The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power domain control. For now this driver only adds power domain support, the more advanced features are not yet supported. The driver implements the generic PM domain device tree bindings, the first user will most likely be the Mediatek AFE audio driver.

Instead of depends on a specific model, make the driver depends on the generic ARCH_MEDIATEK and enable by default so other Mediatek devices can start using it without flood the Kconfig.
