Add _MCDI_DWORD() which yields an lvalue for the given dword field and change MCDI_DWORD(), MCDI_SET_DWORD() and MCDI_QWORD() to use it. Fold the rather trivial MCDI_PTR2() into MCDI_PTR() and _MCDI_DWORD(). Remove MCDI_SET_DWORD2() and MCDI_QWORD2(). MCDI_DWORD2() should also go, but it still has one user which we'll get rid of later. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
