At present the early timer init happens as soon as driver mode is set up. This makes it impossible to do any in that needs driver model but must run before devices are problem (as needed with Intel's FSP-S, for example).
In any case it is not a good idea to tie probing of particular drivers too closely to the DM init.
Create a new function to init the timer and put it a bit later in the sequence.
