This is because QEMU only supports TPM device emulation on x86.
To add it to aarch64 somebody would have to investigate what the
hardware interface for TPM ought to be on aarch64 hardware, and
then implement an emulation of it and add that to the 'virt'
board. (It would probably share a lot of the implementation with
the current x86 TPM, obviously.)

Hmm, actually a quick grep suggests we have some TPM support
for PPC as well (via a hypercall interface). The rest of
my answer still stands, though.
