Run an early SoC reset hook.
Run a SoC-specific hook in the reset/startup code (__start).
A custom hook soc_reset_hook() is executed at the beginning of the
startup code (__start). soc_reset_hook() must be implemented by the SoC.
A custom hook soc_reset_hook() will be executed near the beginning
of the architecture-specific startup code, after hardware has been
configured (as required by CONFIG_INIT_ARCH_HW_AT_BOOT), a stack
pointer has been loaded and the architecture's own resume logic
has executed (if CONFIG_PM_S2RAM is enabled). Because this hook
runs after the resume logic, it is not called when the system
resumes from a suspend-to-RAM power state.
