[PATCH v2 02/10] sandbox: tpm: Tidy up reading and writing of device state

[Simon Glass]

At present this code assumes that the TPM data has been read but this may
not be the case. Refactor the code to use a separate pointer so we know
the current state of the data.

Add error checking for the data size.
