drivers/i2c/tpm: Allow sleep durations to be set by the chip

Allow the sleep durations used by the driver to be set by the
specific chip so they can be tuned appropriately.

Since we need to read the chip id to know the values use very
conservative defaults for the first command and then set it
to the current values by default.
