drm/amd/display: Remove FPU guards from the DML folder 



As part of the programming expectation for using DML functions, DC
requires that any DML function invoked outside DML uses:

 DC_FP_START();
 ... dml function ...
 DC_FP_END();

Additionally, all the DML functions that can be invoked outside the DML
folder call the function dc_assert_fp_enabled(), which is responsible
for triggering a warning in the case that the DML function was not
guarded by the DC_FP_START/END. For this reason, call DC_FP_START/END
inside DML is wrong, and this commit removes all of those references.
