Add a caching layer for the TPM established flag so that we don't

What's the impact? Isn't this just a "small" optimization? Iotw, why
is this for-2.11?
The TIS has a register that contains this flag and that's being polled quite
frequently. So it generates a lot of traffic to the emulator. This caching
layer gets rid of most of the traffic.
I didn't notice any problem when doing my tests, I guess Amarnath
niether. perhaps it's best to delay for after 2.11.
