Christophe Leroy 31699c0624 powerpc/8xx: Fix software emulation interrupt 
[ Upstream commit 903178d0ce6bb30ef80a3604ab9ee2b57869fbc9 ]

For unimplemented instructions or unimplemented SPRs, the 8xx triggers
a "Software Emulation Exception" (0x1000). That interrupt doesn't set
reason bits in SRR1 as the "Program Check Exception" does.

Go through emulation_assist_interrupt() to set REASON_ILLEGAL.

Fixes: fbbcc3bb139e ("powerpc/8xx: Remove SoftwareEmulation()")
