drm/amd/display: Fix RISC-V FP configuration in Kconfig

Commit 4652ae7 ("drm/amd/display: Rename DCN config to FP")
renamed DCN config to FP.

Consolidate DRM_AMD_DC_FP selection logic by moving RISCV && FPU
condition from separate DRM_AMD_DC_DCN selection to the main
DRM_AMD_DC_FP conditional statement.
