When building a system that has both TPL and SPL_OS_BOOT, code which tests for CONFIG_SPL_OS_BOOT will be built and enabled in TPL, which is not correct. While there is no CONFIG_TPL_OS_BOOT symbol at this time (and likely will not ever be) we can use CONFIG_IS_ENABLED(OS_BOOT) in these common paths to ensure we only compile these parts in the SPL case.
