mmc: dw_mmc: Allow lower TMOUT value than maximum
The TMOUT register is always set with a full value for every transfer,
which (with a 200MHz clock) will give a full DRTO of ~84 milliseconds.
This is normally good enough to complete the request, but setting a full
value makes it impossible to test shorter timeouts, when for example
testing data read times on different SD cards.
Add a function to set any value smaller than the maximum of 0xFFFFFF.
