tpm: tis_i2c: Fix sanity check interrupt enable mask
[ Upstream commit 561d6ef75628db9cce433e573aa3cdb6b3bba903 ]
The sanity check mask for TPM_INT_ENABLE register was off by 8 bits,
resulting in failure to probe if the TPM_INT_ENABLE register was a
valid value.
Fixes: bbc23a07b072 ("tpm: Add tpm_tis_i2c backend for tpm_tis_core")
