[Qemu-trivial] [PATCH] tpm: Move memory initialization into realize function

[Stefan Berger]

From: Stefan Berger <address@hidden>

Move the memory initialization into the DeviceClass realize function due to
isa_address_space crashing if called in the instance init function.
A recent change must have changed the order in which structures are
initialized so that this move is now necessary.
