("powerpc/8xx: Remove 8xx specific "minimal FPU emulation""). But that
commit didn't remove all code depending on that symbol. Do so now.

[PATCH] powerpc/8xx: Remove last traces of 8XX_MINIMAL_FPEMU
The Kconfig symbol 8XX_MINIMAL_FPEMU was removed in commit 968219fa33
(powerpc/8xx: Remove 8xx specific minimal FPU emulation). But that
commit didn't remove all code depending on that symbol. Do so now.
