Thomas Fleury d664ff12af gpu: nvgpu: clip target frequencies in arbiter

It is currently possible to set GPCCLK lower than the
minimum allowed frequency.
Clip target GPCCLK/MCLK according to valid min/max range
in arbiter. We could do this before submitting request to
arbiter, but then we would loose information on the
requested target frequency. Instead, we cache the clock
range in arbiter context, and check target frequency when
running arbiter.
