tpm_tis_core: Turn on the TPM before probing IRQ's
commit 5b359c7c43727e624eac3efc7ad21bd2defea161 upstream.
The interrupt probing sequence in tpm_tis_core cannot obviously run with
the TPM power gated. Power on the TPM with tpm_chip_start() before
probing IRQ's. Turn it off once the probing is complete.
