Xi Ruoyao ebe82c6e75 drm/amd/display: Wrap dcn32_override_min_req_memclk() in DC_FP_{START, END}
[Why]
The dcn32_override_min_req_memclk function is in dcn32_fpu.c, which is
compiled with CC_FLAGS_FPU into FP instructions.  So when we call it we
must use DC_FP_{START,END} to save and restore the FP context, and
prepare the FP unit on architectures like LoongArch where the FP unit
isn't always on.
