GPIO 17 is assigned to both the display reset and a gpio-hog.
The hog will be set up first as it has no dependencies, so your display will fail to probe as it can't claim the reset GPIO. IIRC the core code also checks that all dependencies are available before it even bothers trying to call the driver probe function, which may explain why probe isn't being called automatically.
You can also omit regulators instead of attaching things to vdd_3v3_reg.
You can also do "modinfo panel_sitronix_st7703" to get the list of compatible strings for the module.
