drm/amd/display: dc/dce: add initial DCE6 support (v10)

[Why]
DCE6 chipsets have a lot in common with DCE8, let's start from this

[How]
DCE6 targets are added replicating existing DCE8 implementation.

NOTE: dce_8_0_{d,sh_mask}.h headers used instead of dce_6_0_{d,sh_mask}.h
initial build prototype due to missing DCE6 macros/registers/masks
DCE6 specific macros/registers/masks will be added with later commits

(v2b) removed dce_version cases in dc/dce/dce_clock_source.c and
updated dce60 due to following kernel 5.0 commits:
24f7dd7 ("drm/amd/display: move pplib/smu notification to dccg block")
9566b67 ("drm/amd/display: remove safe_to_lower flag from dc, use 2 functions instead")
4244381 ("drm/amd/display: clean up base dccg struct")
4c5e8b5 ("drm/amd/display: split dccg clock manager into asic folders")
84e7fc0 ("drm/amd/display: rename dccg to clk_mgr")
77f6916 ("drm/amd/display: Remove duplicate header")
9f7ddbe ("drm/amd/display: fix optimize_bandwidth func pointer for dce80")
4ece61a ("drm/amd/display: set clocks to 0 on suspend on dce80")

(v3b) updated dce60 due to following kernel 5.1 commits:
380604e ("drm/amd/display: Use 100 Hz precision for pipe pixel clocks")
32e6136 ("drm/amd/display: Fix 64-bit division for 32-bit builds")
1877ccf ("drm/amd/display: Change from aux_engine to dce_aux")
c69dffa ("drm/amd/display: fix eDP fast bootup for pre-raven asic")

(v4b) updated dce60 due to following kernel 5.2 commits:
e5c4197 ("drm/amd/display: Add plane capabilities to dc_caps")
813d20d ("drm/amd/display: Fix multi-thread writing to 1 state")
ea36ad3 ("drm/amd/display: expand plane caps to include fp16 and scaling capability")
afcd526 ("drm/amd/display: Add fast_validate parameter")

(v5b) updated dce60 due to following kernel 5.3 commits:
e7e10c4 ("drm/amd/display: stop external access to internal optc sync params")
78cc70b ("drm/amd/display: Engine-specific encoder allocation")
dc88b4a ("drm/amd/display: make clk mgr soc specific")
4fc4dca ("drm/amd: drop use of drmp.h in os_types.h")

(v6b) updated dce60 due to following kernel 5.4 commits:
54a9bcb ("drm/amd/display: Fix a typo - dce_aduio_mask --> dce_audio_mask")
9adc805 ("drm/amd/display: make firmware info only load once during dc_bios create")

(v7b) updated dce60 due to following kernel 5.5 commits:
cabe144 ("drm/amd/display: memory leak")
8276dd8 ("drm/amd/display: update register field access mechanism")
f6040a4 ("drm/amd/display: configurable aux timeout support")
bf7f5ac ("drm/amd/display: map TRANSMITTER_UNIPHY_x to LINK_REGS_x")

(v8b) updated dce60 due to following kernel 5.6 commits:
d9e3267 ("drm/amd/display: cleanup of construct and destruct funcs")
f42ea55 ("drm/amd/display: add separate of private hwss functions")

(v9b) updated dce60 due to following kernel 5.8 commits:
bba8289 ("drm/amd/display: code clean up in dce80_hw_sequencer.c")
904fb6e ("drm/amd/display: move panel power seq to new panel struct")
d4caa72 ("drm/amd/display: change from panel to panel cntl")

(v10) Fix up PLL handling for DCE6:
DCE6.0 supports 2 PLLs. DCE6.1 supports 3 PLLs. (Alex)
