ARC: 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 to use the generic rule.

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

Now, "nsim_700" is the default value for CONFIG_BUILTIN_DTB_NAME, rather
than a fallback in case it is empty.
