[PATCH 12/15] sh: migrate to the generic rule for built-in DTB

Masahiro Yamada
2024-09-04T23:48:45Z

Select GENERIC_BUILTIN_DTB when built-in DTB support is enabled.

To keep consistency across architectures, this commit also renames
CONFIG_USE_BUILTIN_DTB to CONFIG_BUILTIN_DTB, and
CONFIG_BUILTIN_DTB_SOURCE to CONFIG_BUILTIN_DTB_NAME.
