Build: Add configuration for doorbell APIs
The doorbell APIs are not widely used.
This patch adds a build configuration for them to save memory by
disabling the APIs.
Corresponding changes are made as well:
1. SFN_BACKEND does not support doorbell - it does not provide the
doorbell APIs, so the config should be disabled by default.
2. The psa_wait in SFN backend can be removed as well since neither
of the API consumer, interrupt or doorbell is enabled.
