Add support for other secure element chips

[shawaj]

In order to provide more manufacturing flexibility, it would be good if we can support now secure element chips.

Specifically:

• Runjet rjgt102wdp8
• Maxim Integrated DS28C36Q+T / DS28C36BQ+T
• TFLXTLS ATECC608B
• TPM2.0 chips
• ARM TrustZone

Will also need updates to https://github.com/NebraLtd/hm-miner and https://github.com/NebraLtd/hm-diag and https://github.com/NebraLtd/hm-config and https://github.com/NebraLtd/hm-gwmfr

This is helped by helium/miner#769

TPM support has a PR in miner and gateway_mfr helium repos.

More info at helium/gateway_mfr#5

Other option...

IMHO, sticking to TPM would be better as it is less of a lock-in. We already got the Secure pHAT that we could re-purpose for this and fit onto a board.

@vpetersson that and TrustZone yes.

FYI here is a RockPi 4b based hotspot using TrustZone dewi-alliance/hotspot-manufacturers#254

We should investigate further on our side
