clk: tegra: Move DFLL thermal boundaries defines

DFLL thermal boundaries are just placeholders that are never set as
trip-points in thermal zone. Boundaries values are irrelevant as long
as they are below/above all others, actually set trip-points. They can
be set low/high enough to be applied for each SoC, and they are not
needed for thermal DT nodes. Therefore moved boundaries definitions
from per-SoC DT bindings headers to common DFLL header.
