drivers/i2c/tpm: Remove vendor.irq

The vendor.irq field was originally intended for use as the TPM 1.2
"command complete" interrupt.  However, all actual coreboot tpm drivers
and hardware use the vendor.status method of checking command completion
instead, and this irq field is not used.

Let's just remove this unused functionality to simplify the code.
