qcom_scm_shm_bridge_enable() is used early in the SCM initialization routine. It makes an SCM call and so expects the internal __scm pointer in the SCM driver to be assigned. For this reason the tzmem memory pool is allocated *after* this pointer is assigned. However, this can lead to a crash if another consumer of the SCM API makes a call using the memory pool between the assignment of the __scm pointer and the initialization of the tzmem memory pool. As qcom_scm_shm_bridge_enable() is a special case, not meant to be called by ordinary users, pull it into the local SCM header. Make it take struct device as argument. This is the device that will be used to make the SCM call as opposed to the global __scm pointer. This will allow us to move the tzmem initialization *before* the __scm assignment in the core SCM driver.
