drm/i915: Stop setting SNB min-freq-table 0 on powersave setup
The min-freq-table is an array of values that match each CPU frequency to
an equivalent GPU frequency. Setting a single value of 0 on init is both
illegal (generates an error from the PCU) and nonsensical. Let's see if
we survive without that error.
