Recently we met an issue on lots of Lenovo thinkpad laptops (those
laptops are not released to market yet), the issue is that the
thinkpad_acpi.ko can't be automatically loaded as before.

Through debugging, we found the HKEY_HID is LEN0268 instead of
LEN0068 on those machines, and the MHKV is 0x200 instead of
0x100. So adding the new ID into the driver.
