drm/amdgpu/display: drop DCN support for aarch64

From Ard:

"Simply disabling -mgeneral-regs-only left and right is risky, given that
the standard AArch64 ABI permits the use of FP/SIMD registers anywhere,
and GCC is known to use SIMD registers for spilling, and may invent
other uses of the FP/SIMD register file that have nothing to do with the
floating point code in question. Note that putting kernel_neon_begin()
and kernel_neon_end() around the code that does use FP is not sufficient
here, the problem is in all the other code that may be emitted with
references to SIMD registers in it.

So the only way to do this properly is to put all floating point code in
a separate compilation unit, and only compile that unit with
-mgeneral-regs-only."

Disable support until the code can be properly refactored to support this
properly on aarch64.

Add DCE6 specific dce60/dce60_clk_mgr.c for DCE6 customization
Code style: reuse all the public functions in dce100/dce_clk_mgr.h header
Code style: use dce60_* static functions as per other DCE implementations
Add dce60_get_dp_ref_freq_khz() w/o using DPREFCLK_CNTL register
Use dce60_get_dp_ref_freq_khz() function in dce60_funcs
Add DCE6 specific dce60_clk_mgr_construct
dc/clk_mgr/dce_clk_mgr.c: use dce60_clk_mgr_construct for FAMILY_SI chipsets
Add Makefile rules for dce60_clk_mgr.o target conditional to CONFIG_DRM_AMD_DC_SI
