Introduce ARCH_NO_SYSDEV_OPS config option (v2)
Introduce Kconfig option allowing architectures where sysdev operations used during system suspend, resume and shutdown have been completely replaced with struct sycore_ops operations to avoid building sysdev code that will never be used. Make callbacks in struct sys_device and struct sysdev_driver depend on ARCH_NO_SYSDEV_OPS to allows us to verify if all of the references have been actually removed from the code the given architecture depends on. Make x86 select ARCH_NO_SYSDEV_OPS. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
