I think we should fix QEMU coding style violations in TPM code.
In particular, mixing of _ and camel case, enum and define values
not all upper case, local variables not all lower case.
This was less of an issue when the violations were contained
within hw/tpm/, but it's more of an issue now that this affects
other code.
