[PATCH] drm/amd/display: include soc._clock_tmp[] into DC's scratch region

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.
