sh: Migrate to the generic rule for built-in DTB

Browse source 
Commit 654102df2a ("kbuild: add generic support for built-in
boot DTBs") introduced generic support for built-in DTBs.

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.
