TPM: Fixup boot probe timeout for tpm_tis driver
commit ec57935837a78f9661125b08a5d08b697568e040 upstream.
When probing the device in tpm_tis_init the call request_locality
uses timeout_a, which wasn't being initalized until after
request_locality. This results in request_locality falsely timing
out if the chip is still starting. Move the initialization to before
request_locality.
This probably only matters for embedded cases (ie mine), a BIOS likely
gets the TPM into a state where this code path isn't necessary.
