Subject: [PATCH] openrisc: migrate to the generic rule for built-in DTB

Commit 654102df2ac2 ("kbuild: add generic support for built-in boot
DTBs") introduced generic support for built-in DTBs.

Select GENERIC_BUILTIN_DTB to use the generic rule.

To keep consistency across architectures, this commit also renames
CONFIG_OPENRISC_BUILTIN_DTB_NAME to CONFIG_BUILTIN_DTB_NAME.
