Subject: [PATCH 06/15] riscv: migrate to the generic rule for built-in DTB
Select GENERIC_BUILTIN_DTB when built-in DTB support is enabled.
To keep consistency across architectures, this commit also renames
CONFIG_BUILTIN_DTB_SOURCE to CONFIG_BUILTIN_DTB_NAME.
Signed-off-by: Masahiro Yamada <masahiroy@...nel.org>
