ARM: tegra11: clock: Add cbus fine granularity region

Added fine granularity region to cbus possible rates. In this region
requested cbus rate is not clipped to dvfs steps, but rounded to fine
granularity resolution. The latter is set as 12MHz, and the region is
defined as 5 resolution steps below the top dvfs rate, assuming this
top rate is reachable on the particular chip bin/sku.
