Add module init and exit functions for the bridge to register and unregister dsi_driver.
Exynos drm driver stack will register the platform_driver separately in the common of it's exynos_drm_drv.c including dsi_driver.
Register again would return -EBUSY, so return 0 for such cases as dsi_driver is already registered.
v1: * none
