TPM: fix TIS device driver locality request

During the initialization of the TPM TIS driver, the necessary locality has
to be requested earlier in the init-process.  Depending on the used TPM
chip, this leads to wrong information.  For example: Lenovo X61s with Atmel
TPM:

tpm_tis 00:0a: 1.2 TPM (device-id 0xFFFF, rev-id 255)

But correct is:

tpm_tis 00:0c: 1.2 TPM (device-id 0x3203, rev-id 9)

This short patch fixes this issue.
