[Buildroot] [PATCH 1/2] package/tpm2-tools: propagate BR2_PACKAGE_TPM2_TSS_FAPI dependencies

[Thomas Petazzoni via buildroot]

In commit 5394df6400912efa7da4f97c7ea68a81a9f77c1d ("package/tpm2-tss:
add Mbed-TLS crypto backend support"), a depends on
!BR2_PACKAGE_MBEDTLS was added to BR2_PACKAGE_TPM2_TSS_FAPI, but this
new dependency was not properly propagated to the reverse
dependencies, causing kconfig warnings such as:

WARNING: unmet direct dependencies detected for BR2_PACKAGE_TPM2_TSS_FAPI
  Depends on [n]: BR2_PACKAGE_TPM2_TSS [=y] && BR2_TOOLCHAIN_HAS_SYNC_4 [=y] && !BR2_PACKAGE_MBEDTLS [=y]
  Selected by [y]:
  - BR2_PACKAGE_TPM2_TOOLS_FAPI [=y] && BR2_PACKAGE_TPM2_TOOLS [=y] && BR2_TOOLCHAIN_HAS_SYNC_4 [=y]

This commit properly propagates this new dependency to
BR2_PACKAGE_TPM2_TOOLS_FAPI, fixing the kconfig warning.

[Buildroot] [PATCH 2/2] package/tpm2-tss: do not show comment when dependencies are not met

[Thomas Petazzoni via buildroot]

Commit 5394df6400912efa7da4f97c7ea68a81a9f77c1d ("package/tpm2-tss:
add Mbed-TLS crypto backend support") added a dependency to
BR2_PACKAGE_TPM2_TSS_FAPI, and a comment about this
dependency. However, the comment is shown even if other
architecture-related dependencies are not met.

This commit fixes that by only displaying the comment when relevant,
i.e when BR2_TOOLCHAIN_HAS_SYNC_4.
