Currently, we are using soc._clock_tmp[] to temporarily store and modify data from soc.clock_limits[] before copying it back into soc.clock_limits[] (because modifying data directly in soc.clock_limits[] causes unintended behavior). However, this approch has a number of downsides, such as: 1. struct _vcs_dpi_soc_bounding_box_st's creation/destruction aren't well defined (which could mean more unintended behavior). 2. Throwing temp varibles in structs everywhere doesn't make for a particularly readable codebase. For these reasons, we should get rid of soc._clock_tmp[] by defining a struct scratch within struct dc that, contains within it all of the temporary varibles (including _clock_tmp[]) such that it is obvious how they are intended to be used.
