spmi: add a spmi driver for Apple SoC The connected PMU contains several useful nvmem cells such as RTC offset, boot failure counters, reboot/shutdown selector, and a few others. In addition M3+ machines have their USB-PD controller connected via SPMI.

spmi: apple: Add "apple,t8103-spmi" compatible After discussion with the devicetree maintainers we agreed to not extend lists with the generic compatible "apple,spmi" anymore [1]. Use "apple,t8103-spmi" as base compatible as it is the SoC the driver and bindings were written for.
