[PATCH] hw/tpm: TIS on sysbus: Remove unsupport ppi command line option

[Stefan Berger]

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
[...]
Segmentation fault (core dumped)
