TpmError headers

[NickDarvey]

There's references to TpmError.h but I can't find that in this repo, nor in ms-tpm-20-ref. Where can I find these?

optee_ftpm/platform/EPS.c

Line 46 in ea90e5a

#include "TpmError.h"

This commit microsoft/ms-tpm-20-ref@ee21db0 removed it.

The latest on optee_ftpm needs to be built with a certain version of ms-tpm-20-ref, currently it's set to 98b60a44aba79b15fcce1c0d1e46cf5918400f6a since that was the latest when I started to work in optee_ftpm.
This is tracked automatically when using the repo setup, for an example see https://optee.readthedocs.io/en/latest/building/devices/qemu.html#qemu-v8

Given that this is the case, is there a particular reason not to just reference microsoft/ms-tpm-20-ref@98b60a44 as a submodule in this repo, rather than requiring it to be checked out separately to the correct version?

We use repo instead of git submodules.
