drivers/tpm/tpm_tis_sandbox.c: Fix uninitialized variable use

In rollback_space_kernel we were not initializing the reserved fields
which should be for safety sake, and doing memset here means we don't
need to set the version field specifically either.

lib/crc8: Add crc start value

To make the usage of this function more flexible, lets add the CRC start
value as parameter to this function. This way it can be used by other
functions requiring different start values than 0 as well.

For non-zero CRC start values to work, I've reworked the function a bit.
The new implementation is copied from the Linux version in
drivers/i2c/i2c-core.c / i2c_smbus_pec(). Which supports non-zero
CRC stating values.

I've double-checked that the results for zero starting values are
identical to the results from the original version of this function.

sandbox: tpm: Add TPM emulation

Add a simple TPM emulator for sandbox. It only supports a small subset of
TPM operations. However, these are enough to perform common tasks.

Note this is an initial commit to get this working, but it could use
cleaning up (for example constants instead of open-coded values).
