When compiling with Clang on LoongArch, there exists the following objtool
warning in drivers/gpu/drm/amd/display/dc/basics/fixpt31_32.o:
dc_fixpt_recip() falls through to next function dc_fixpt_sinc()
This is because dc_fixpt_from_fraction() is inlined in dc_fixpt_recip()
by Clang, given dc_fixpt_from_fraction() is not a simple function, just
mark it noinline to avoid the above issue.
