drm/amd/display: re-indent dpp401_dscl_program_isharp()

Smatch complains because some lines are indented more than they should
be.  I went a bit crazy re-indenting this.  ;)

The comments were not useful except as a marker of things which are left
to implement so I deleted most of them except for the TODO.

I introduced a "data" pointer so that I could replace
"scl_data->dscl_prog_data." with just "data->" and shorten the lines a
bit.  It's more readable without the line breaks.

I also tried to align it so you can see what is changing on each line.
