dcn10_validate_bandwidth is only used on dcn10 files, but is declared in dcn_calcs files. Rename dcn10_* to dcn_* in calcs, remove DC_FP_* wrapper inside DML folder and create an specific dcn10_validate_bandwidth in dcn10_resources that calls dcn_validate_bandwidth and properly wraps that FPU function with DC_FP_* macro.

Just for the record: That's not really usual kernel coding style, but that's not topic of this patch set.
Yeah. I didn't change the code style to ease any version conflict management.

Thanks!
And it would be really nice if we could make the DC_FP_* macros somehow fail in the dml folder.
And if we include a kind of dc_assert_fp_disabled() in the dc_fpu_begin() (DC_FP_START) - more or less the reverse of dc_assert_fp_enabled(). Does it meet the `make the DC_FP_* macros somehow fail in the dml folder` ? It is not restricted to the dml folder, but I think it would work similarly... Does it make sense?

Thanks, Christian.
