Even though there's now a TPL_DM configuration option, the spl logic still checks for SPL_DM and thus does not pick up the proper config option. This introduces the use of CONFIG_IS_ENABLED(DM) in spl.c to always pick up the desired configuration option instead of having a hard-coded check for the SPL variant.
