With recent rework, trusted keys are no longer limited to TPM as trust
source. The Kconfig symbol is unchanged however leading to a few issues:
- TCG_TPM is required, even if only TEE is to be used
- Enabling TCG_TPM, but excluding it from available trusted sources
is not possible
- TEE=m && TRUSTED_KEYS=y will lead to TEE support being silently
dropped, which is not the best user experience
Remedy these issues by introducing two new boolean Kconfig symbols:
TRUSTED_KEYS_TPM and TRUSTED_KEYS_TEE with the appropriate
dependencies.
Any new code depending on the TPM trusted key backend in particular
or symbols exported by it will now need to explicitly state that it
depends on TRUSTED_KEYS && TRUSTED_KEYS_TPM
The latter to ensure the dependency is built and the former to ensure
it's reachable for module builds. There are no such users yet.
