lib: sbi: Align system suspend errors with spec

2023-06-04T09:48:40Z

The spec says sbi_system_suspend() will return SBI_ERR_INVALID_PARAM when "sleep_type is reserved or is platform-specific and unimplemented" and SBI_ERR_NOT_SUPPORTED when sleep_type "is not reserved and is implemented, but the platform does not support it due to one or more missing dependencies." Ensure SBI_ERR_INVALID_PARAM is returned for reserved sleep types and that the system suspend driver can choose which of the two error types to return itself by returning an error from its check function rather than a boolean.
