The original patch which added the quirk would apply to all AAEON machines,
which might or might not be valid.
The issue was discovered on UPX-i11 (TigerLake), it is not known if the
i12 (AlderLake) version is affected.
UP2 (ApolloLake) does not even have TMP module (no TPM drivers probing
and confirmed by dmidecode).
Let's make the quirk to be applicable for UPX-i11 (UPX-TGL01) only.

Another nit, the official spelling of the SOC names is with a space, for
example, Tiger Lake [1].

I will correct this and the ADL, APL spelling also.
