dm: tpm: Remove every compilation switch for TPM driver model
As every TPM drivers support UCLASS_TPM, we can only rely on DM_TPM functions. This simplify a bit the code. Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Reviewed-by: Tom Rini <trini@konsulko.com> Acked-by: Simon Glass <sjg@chromium.org>
