<title>drm/amd/display: move FPU operations from dcn21 to dml/dcn20 folder</title>

<content type='text'>
dml/dcn20_fpu file centralizes all DCN2x functions that require FPU access.
Therefore, this patch moves FPU-related code from dcn21 to dcn20_fpu. These
include:
- dcn21_populate_dml_pipes_from_context()
- dcn21_validate_bandwidth_fp() and related:
  - dcn21_calculate_wm(),
  - patch_bounding_box(),
  - calculate_wm_set_for_vlevel()
- renaming update_bw_bounding_box() to dcn21_update_bw_bounding_box(), move
to dcn20_fpu with related static function construct_low_pstate_lvl()

Also, make dcn21_fast_validate_bw() public in dcn21_resource as it is called
by dcn21_validate_bandwidth_fp() now in dcn20_fpu.

Reuse dcn20_fpu_adjust_dppclk() in dcn21_fast_validate_bw() as it isolates
the same FPU operation.

Include dchubbub.h as it is required in dcn21_populate_dml_pipes_from_context()

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.

[Why &amp; How]
Program modulo with ref dpp clk Mhz/10.
Program phase with pipe dpp clk Mhz /10.
DMUB FW could use these value to determine optimization clk
for PSR power saving.

This adds ARM64 support into the DCN. This mainly enables support
for Navi graphics cards. The dcn10 changes haven't been tested,
since I don't have the relevant hardware available, but there
is no way to conditionally disable them, so I've done them anyway.

<id>urn:sha1:16a9dea110a67d62401ffeac4828cabdedec7548</id>
<content type='text'>
DCN requires floating point support to operate.  Add the appropriate
x86/ppc64 guards and FPU / AltiVec / VSX context switches to DCN.

Note that the current DC20 code doesn't contain all required FPU
wrappers on x86 or POWER, so this patch is insufficient to fully
enable DC20 on POWER.

v2: s/X86_64/X86/g to retain previous behavior.

<title>drm/amd/display: cleanup of function pointer tables</title>

<content type='text'>
[Why]
It is becoming increasingly hard to figure out which
function is called on the different DCN versions

[How]
1. Make function pointer table init in its own init.c file
2. Remove other scenarios in hwseq.c file that need to
include headers of other DCN versions. (If needed,
it should have been done via the function pointers)
