dell-laptop: use dell_smbios_find_token() instead of find_token_location()
Replace all uses of find_token_location() with dell_smbios_find_token() to avoid directly accessing the da_tokens table. Signed-off-by: Michał Kępień <kernel@kempniu.pl> Reviewed-by: Pali Rohár <pali.rohar@gmail.com> Signed-off-by: Darren Hart <dvhart@linux.intel.com>
