amdgpu: expand Stage 2 to 10 DCN files (DCN20+DCN30+DCN31)

Browse Source 
Add dpp, mmhubbub include paths. Add ilog2 macro.
10 of 11 tested DCN files now compile with 0 errors.
dnc30_cm_common.c excluded — dcn30_cm_common.h missing from Linux 7.1 tree.

# Stage 2: DCN hardware display files
#
# These DCN 3.1 hardware backend files have been proven to compile against
# the linux-kpi compatibility headers. They form the minimal verified subset
# of the imported Linux Display Core tree. Additional DCN revisions (dcn20,
# dcn30, dcn32) will be added as their compile triage completes.
