drm/amd/display: Use pre-allocated temp struct for bounding box update
[Why] There is a theoretical problem in prior patches for reducing the stack size of *update_bw_bounding_box() functions. By modifying the soc.clock_limits[n] struct directly, this can cause unintended behavior as the for loop attempts to swap rows in clock_limits[n]. A temporary struct is still required to make sure we stay functinoally equivalent. [How] Add a temporary clock_limits table to the SOC struct, and use it when swapping rows.
