While this is technically correct for all I can tell, could you
convert it to use __initconst platform_device_info and
platform_device_register_full() instead?

statically declaring platform_devices has been frowned upon for a long
time (even though a lot of arm platforms still do it), and statically
declaring the dma mask seems worse to me (and yes, I realize we also
do that elsewhere).
