dm: x86: Allow TSC timer to be used before DM is ready
With bootstage we need access to the timer before driver model is set up.
To handle this, put the required state in global_data and provide a new
function to set up the device, separate from the driver's probe() method.
This will be used by the 'early' timer also.
