Add a "ppi" boolean property (default: true) to tpm-tis-device.
When ppi=off the RAMBlock is never registered and the migration
stream omits "tpm-ppi", restoring backward compatibility.
Move sysbus_init_mmio() calls from instance_init to realizefn so
the memory regions are initialized before being registered. When
ppi=off, the PPI MMIO region is simply not exposed.
Fixes: 46cd2c1050 ("hw/tpm: add PPI support to tpm-tis-device for ARM64 virt")
