    hw/tpm: TIS on sysbus: Remove unsupport ppi command line option
    
    The ppi command line option for the TIS device on sysbus never worked
    and caused an immediate segfault. Remove support for it since it also
    needs support in the firmware and needs testing inside the VM.
    
    Reproducer with the ppi=on option passed:
    
    qemu-system-aarch64 \
       -machine virt,gic-version=3 \
       -m 4G  \
       -nographic -no-acpi \
       -chardev socket,id=chrtpm,path=/tmp/mytpm1/swtpm-sock \
       -tpmdev emulator,id=tpm0,chardev=chrtpm \
       -device tpm-tis-device,tpmdev=tpm0,ppi=on
    [...]
