ideapad-laptop: Constify DMI table for real!

This is a follow-up patch to commit 49458e83 ("ideapad-laptop:
Constify DMI table and other r/o variables") to do what its commit
message says. The actual commit differs from the patch posted at
https://www.mail-archive.com/platform-driver-x86@vger.kernel.org/msg05340.html
significantly, probably due to a bad merge conflict resolution. Fix up
the mess and constify the DMI table for real and fix the bogus
double-const of ideapad_rfk_data[].
