This is because allthough CONFIG_MATH_EMULATION is selected, Exception 800 calls unknown_exception().
Call emulation_assist_interrupt() instead.

powerpc: Remove CONFIG_FSL_BOOKE
PPC_85xx is PPC32 only. PPC_85xx always selects E500 and is the only PPC32 that selects E500. FSL_BOOKE is selected when E500 and PPC32 are selected.
So FSL_BOOKE is redundant with PPC_85xx.
Remove FSL_BOOKE.
And rename four files accordingly.
cpu_setup_fsl_booke.S is not renamed because it is linked to PPC_FSL_BOOK3E and not to FSL_BOOKE as suggested by its name.
