The TMOUT register is initted to 0xffffffff at probe time but isn't
initted after suspend/resume. Add an init of this value.
No problems were observed without this (it will also get initted in
__dw_mci_start_request if there is data to send), but it makes the
register dump before and after suspend clean.
