The Qualcomm Command DB driver seems to have been indirectly enabled by the Qualcomm DRM driver and up until the introduction of '778279f4f5e4 ("soc: qcom: cmd-db: allow loading as a module")' this resulted in the driver "always" being builtin on arm64. But with the introduction of said change it, and all other RPMH related drivers, becomes =m. The immediate result is that the uart driver fails to probe, which depending on userspace's dependency on the presence of /dev/console might be fatal. For systems getting past this the default timeout of 0 seconds for probe deferral of many subsystems causes the system to be completely useless. So, make Command DB builtin.
