powerpc/85xx: Fix math emulation exception
Booting mpc85xx_defconfig kernel on QEMU leads to:
Bad trap at PC: fe9bab0, SR: 2d000, vector=800
awk[82]: unhandled trap (5) at 0 nip fe9bab0 lr fe9e01c code 5 in libc-2.27.so[fe5a000+17a000]
awk[82]: code: 3aa00000 3a800010 4bffe03c 9421fff0 7ca62b78 38a00000 93c10008 83c10008

Trace/breakpoint trap
WARNING: no useful console
This is because allthough CONFIG_MATH_EMULATION is selected,
Exception 800 calls unknown_exception().
Call emulation_assist_interrupt() instead.
