[capstone2llvmir]: unhandled branch instruction format #1

I have raw binary firmware file from PowerPC e200z4, which is 32bit PowerPC big endian CPU. And when I ran retdec-decompiler.py I got output

```
Running phase: Initialization ( 0.01s )
Running phase: LLVM ( 0.01s )
Running phase: Providers initialization ( 0.01s )
Running phase: Input binary to LLVM IR decoding ( 0.11s )
[capstone2llvmir]: unhandled branch instruction format #1
Error: Decompilation to LLVM IR failed
```

If it helps, then this is the list of bd* instructions I got from `powerpc-linux-gnu-objdump -m powerpc -M e200z4 -D -b binary -EB firmware.bin` on that file

Lot of them could be just data interpreted as instructions. I cannot insert full file, but I can send some parts.
Thanks in advance
