PS3, Line 19: Also fix some mainboards that selected TPM2 directly, which they're not
            : supposed to do (that's what MAINBOARD_HAS_TPM2 is for), and add a
            : missing dependency to TPM_CR50 so it is set correctly for a NO_TPM
            : scenario.
It’d be great if you split this into a separate commit.
