soc: qcom: rpmh: Allow RPMH driver to be loaded as a module
This patch allow the rpmh driver to be loaded as a permenent module. Meaning it can be loaded from a module, but then cannot be unloaded. Ideally, it would include a remove hook and related logic, but the rpmh driver is fairly core to the system, so once its loaded with almost anythign else to get the system to go, the dependencies are not likely to ever also be removed. So making it a permenent module at least improves things slightly over requiring it to be a built in driver.
