ANDROID: soc: qcom: cmd-db: Allow COMMAND_DB driver to be loaded as a module

Browse source 
This patch allow the Qcom cmd-db driver to be loaded as a
permanent module. It can be loaded as a module, but can't
be unloaded. That should be OK because few core Qcom drivers,
mainly RPMH, which depend on cmd-db are configured as
permanent modules as well.

This version is only for android11-5.4. For android-mainline
and android12-5.4, the fix will come from upstream.
