Subject: ALSA: hda - add a new condition to check if it is thinkpad

From: Hui Wang <hui.wang@canonical.com>

commit 2ecb704a1290edb5e3d53a75529192e7ed2a1a28 upstream.

Latest Thinkpad laptops use the HKEY_HID LEN0268 instead of the
LEN0068, as a result neither audio mute led nor mic mute led can work
any more.

After adding the new HKEY_HID into the is_thinkpad(), both of them
works well as before.
