Due to usage of PREBOOT in Kconfig, macro CONFIG_PREBOOT is always defined when CONFIG_USE_PREBOOT is enabled. In case CONFIG_PREBOOT is not explicitly enabled it is set to empty C string and therefore '#ifdef CONFIG_PREBOOT' guard does not work. Fix this issue by introducing a new Kconfig symbol PREBOOT_DEFINED which cause to define new C macro CONFIG_PREBOOT_DEFINED only when CONFIG_PREBOOT is really defined.
Change usage of '#ifdef CONFIG_PREBOOT' by '#ifdef CONFIG_USE_PREBOOT' for code which checks if preboot code would be called and by '#ifdef CONFIG_PREBOOT_DEFINED' for defining preboot code.
