Tested by running the following on a grunt board (Barla) in dev mode
together with CL:1496910:
sudo crosvm run \
--root rootfs.ext4 \
--socket crosvm.sock \
--seccomp-policy-dir seccomp \
--software-tpm \
-p init=/bin/bash \
-p panic=-1 \
vmlinux.bin
and confirming that /dev/tpm0 and /dev/tpmrm0 are present in the VM.
I needed to override the common device policy's `open` and `openat` and
was not able to get that working with the existing @include.
Note: untested on arm.
