As I've previously mentioned, TPM components currently are provided by 
multiple layers:

1. meta-security/meta-tpm - a community set of layers, backed by YP, active
2. meta-secure-core/meta-tpm2 - WindRiver vendor set of layers, active
3. meta-measured - personal layer, no longer active for 4 years

Just to note that meta-arm already sets up dynamic-layer with own bbappend 
fixes for #2 meta-secure-core/meta-tpm2:
https://git.yoctoproject.org/meta-arm/tree/meta-arm/dynamic-layers/meta-tpm2/recipes-tpm/tpm2-tools

But I'm fine for meta-ti to go with #1 meta-security/meta-tpm.

That said - have you tested your change? I'm afraid it won't work.

You are only setting up meta-security, which is a top-level layer, parsing 
only recipes*/*/*.bb and recipes*/*/*.bbappend - please note that TPM recipes 
reside in meta-tpm sub-layer called "tpm-layer":
https://git.yoctoproject.org/meta-security/tree/meta-tpm/conf/layer.conf
