drm/amd/display: move remaining FPU code to dml folder

pipes[pipe_cnt].pipe.src.dcc_fraction_of_zs_req_luma = 0;
pipes[pipe_cnt].pipe.src.dcc_fraction_of_zs_req_chroma = 0;
these two operations in dcn32/dcn32_resource.c still need to use FPU,
This will cause compilation to fail on ARM64 platforms because
-mgeneral-regs-only is enabled by default to disable the hardware FPU.
Therefore, imitate the dcn31_zero_pipe_dcc_fraction function in
dml/dcn31/dcn31_fpu.c, declare the dcn32_zero_pipe_dcc_fraction function
in dcn32_fpu.c, and move above two operations into this function.
