You can use platform_device_alloc() to dynamically allocate a device, which
you will then initialize with resources and platform_device_register().
A better solution is usually:

struct platform_device *platform_device_register_simple(
const char *name, int id,
struct resource *res, unsigned int nres);
char *name, unsigned id,
struct resource *res, unsigned nres);

You can use platform_device_register_simple() as a one-step call to allocate
