clk: Always vote INT_MAX as maximum voltage for a rail

Browse Source 
Update regulator set voltage requests to always send INT_MAX as the max
voltage, this will ensure clocks never set any upper bound request for any
voltage regulator.

This avoids regulator_set_voltage() failures arising from different
regulator consumers specifying different max voltages.
