ec/lenovo/h8: Config the ec hardware ids for newer thinkpads

Currently coreboot is using the ec hardware id IBM0068 for all
thinkpads, but for newer thinkpads the id maybe LEN0068 or LEN0268.
On Windows, the Lenovo Vantage app can't get battery details when using
IBM0068. This patch config this id by motherboard. The hardware IDs for
the following models can be found by searching for disassembled
dsdt.asl on vendor BIOS:
(But this info is not easy to find online. So I only changed some of
the thinkpads.)
