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 (Tiger Lake), it is not known if the
i12 (Alder Lake) version is affected.
UP2 (Apollo Lake) does not even have TPM module (no TPM drivers probing
and confirmed by dmidecode).
Let's make the quirk to be applicable for UPX-i11 (UPX-TGL01) only.
Fixes: 95a9359ee22f ("tpm: tpm_tis: Disable interrupts for AEON UPX-i11")
